Okay magnet question for physics Farkers:

Magnetic fields definitionally can't do work. I get that, and I remember in my E&M class going over a dozen cases where it looks like an electromagnet is doing work, but if you squint and look sideways, it's really not. But I don't remember how they explained that permanent magnets don't do work when they lift things. It's been bugging me.

Equal and opposite actions. The magnet is pulling an object towards it (and from another frame of reference, that object is pulling the magnet towards it)

To lift an object, something must be restraining the magnet. As the magnet and the object it is pulling to it get closer, that restraint will either deform, move, or have work done to it to keep the magnet in place

Electromagnets: "When all the magnetism comes from currents, the magnetic field does no work. However, by steering the electrons in new directions it can cause them to bounce off things and do work. So the magnetic field causes work but doesn't do it itself. Think of it as being sort of like a boss. "

I thought the same thing.  I never bothered to look up the answer to the question at the time but basically the ICP guy had a valid question and we're all the stupid ones for making fun of him.  Farking magnets, how do they work?  We can completely explain the effect but don't actually know what causes it.

The restriction is really on doing net work in a cyclical process. A piece of iron moving toward a magnet is like a ball rolling down a hill; it's moving to a state of lower potential energy, and work is done on it in the process. However the only way to return the object to its starting position is to supply an even larger amount of energy that what you were able to extract from it.
 
2013-09-25 12:35:05 AM  
Wow, some of you guys are really over-thinking the Work thing.  Whenever a force is applied to move something from here to there, a quantity of energy is required, termed "work."  So of course if that force originates from the magnetic field, then it "does work."

Of course you can follow the breadcrumbs and it gets more complicated.  See Richard Feynman's explanation.

These seem... not right to me. Because by definition a magnetic field cannot do work. The equation of force due to a magnetic field is F = v x B. The equation for work is W = ∫F ⋅ dL. So the work done by a magnetic field would be W = ∫(v x B) ⋅ dL which necessitates that neither v nor B are parallel to L because then the dot product would be zero. So if it's really a magnetic field, it really can't do work, and there's no "but only if it does a small amount of work" clause.

Unless I'm missing something important, which I certainly grant is possible.

There is exactly one magnetic monopole in the universe. It passed through a detector in February 1982 and has not been seen since.

A magnetic field can't do work on a free electric charge, but it can apply a torque to a current loop and interact with atoms in other ways which do perform work. If you don't believe me, then I invite you to put your head in front of the business end of one of these devices.

Yeah I said that electro-magnets aren't really doing work. This is because really it's the wire, reacting to the magnetic field. So the field is causing the wire to do work. 
In the natural case the magnets within the magnetized object are doing work on each other by pushing and pulling for positions (the fighting domains metaphor from the video), so technically it's work. 

Magnets. Fark they are complicated.

To be fair, science does have an answer to how magnets work, they can describe the function of magnets in great detail.  They just don't know why magnets work.  "Electrons have polarity.  Why?  That's just the way it is."  Yes, frustrating.

Sure they can do work, the standard "perpetual motion machine" scam depends on magnetic arrangements that overcome air resistance and mechanical resistance by disordering the domains.

In the case of individual electrons, it has to do with the conservation of orbital momentum in the various electronic energy levels.

In the case of "magnets" in the macro-sense, e.g. why some materials form domains and some don't, it has to do with the natural crystal structure of various elements and compounds and the resulting alignment of d-level orbitals.  Some geometric interactions of half-full orbitals achieve lower energy when the interacting orbitals have the same spin, so domains are preferred.  Other (most) geometries have spin-interactions governed by more general spin coupling so they form counter-spin pairs/grids and cancel the net field to zero.

//Short answer: actually, yeah, we know why, and bulk magnetism isn't really a result of electrons so much as interatomic orbital structure.

I disagree. For two reasons.  First of all there are a lot of why's being explained in both the minute physics video and the veritasium videos.  The real reason those explanations are not satisfying to the general public is that the language of physics is math.  To understand the physics you need to understand the math first.  English is not a good medium for transferring knowledge of physics which is why people often resort to analogies to explain physics.  And those analogies are always flawed in some way (sometimes badly flawed as Feynman points out about the rubber band analogy in the video linked to above).  Secondly I disagree that it is frustrating.  You can always keep asking why.  Eventually you will get to something that is not well understood to current science.  For example one can explain that magnetic fields are really electrical fields viewed in a different (moving) reference frame.  That is relativity explains why the magnetic field is really an electric field.  Moving charges create magnetic fields.  One can explain that quantum mechanics tells us that the electrons in atoms can have a fixed angular momentum.  In a semi classical view point the electron is orbiting the nucleus, so it's moving, so it's producing a magnetic field.  One can explain how some elements are magnetic and some are not, how magnetic materials often form domains, how crystal structure can effect magnetism, etc.  But if the listener keeps asking why, eventually you get to a question that science (or possibly the person doing the explaining) can't explain.  Or has not yet explained.  Take the intrinsic magnetic moment of an electron.  Why does it exist?  My answer would be it just does or better yet I don't know.  But that is not frustrating!  It's interesting.  It's science.  It's the whole point of science.  Asking questions (well asking the right question-the one with the answer that you have some hope of discovering) is what *is* science.  How can you call that frustrating?

The "how" of magnets has been well understood for 150 years and that's what's in the quote from ICP.  The point is invalid, they're not lying.  Any "why" questions you can think of may or may not be useful or relevant to a better understanding.  Both the "how" and the "why" will be better explained by scientists anyway.   Scientists struggling to explain (valid) why questions is still mankind's best attempt at an answer so I don't know why anyone would be upset.  ICP should be ridiculed until the day they die for that nonsense.

Oh and you "deeply respect the scientific method"?  Bull.  I've seen you derping it up in climate change threads.  Here's a gem of yours:

Whether the average temperature of the Earth is rising or not, there's not really much we can do about it (either to speed it up OR slow it down OR change it in any way, really). I'm not sure how making Al Gore richer is supposed to help the world. Buy carbon credits so you can live your life as normal while people elsewhere sacrifice unnecessarily - yeah, sounds like a pretty typical Western course of action. AGW is BS and if you buy in to it, you're one dumb SOB (NTTAWWT).

That's a lot of potato in one small comment.

You're right.  My teachers have been lying to me all this time about "knowing" the value of pi, when in fact it keeps changing as we calculate more digits.  I'd better just stop using the number in any calculations until we have it calculated to 100% accuracy.  Thanks for warning me, I might have made some huge mistakes.

I don't understand. If F is not perpendicular to L, then vxB is not perpendicular to L, and the magnet does work.

I guess I'm thinking about it analogously to a force parallel to the ground towing a weight up an inclined plane. The force may be perpendicular to gravity, but it is not perpendicular to the direction of movement of the weight.

The "how" of magnets has been well understood for 150 years and that's what's in the quote from ICP.  The point is invalid, they're not lying.  Any "why" questions you can think of may or may not be useful or relevant to a better understanding.  Both the "how" and the "why" will be better explained by scientists anyway.   Scientists struggling to explain (valid) why questions is still mankind's best attempt at an answer so I don't know why anyone would be upset.  ICP should be ridiculed until the day they die for that nonsense.

Oh and you "deeply respect the scientific method"?  Bull.  I've seen you derping it up in climate change threads.  Here's a gem of yours:

Whether the average temperature of the Earth is rising or not, there's not really much we can do about it (either to speed it up OR slow it down OR change it in any way, really). I'm not sure how making Al Gore richer is supposed to help the world. Buy carbon credits so you can live your life as normal while people elsewhere sacrifice unnecessarily - yeah, sounds like a pretty typical Western course of action. AGW is BS and if you buy in to it, you're one dumb SOB (NTTAWWT).

That's a lot of potato in one small comment.


So where is the experimental data? Oh, right, there isn't any, the models don't predict anything, and the people involved have been caught trying to cover that up. But sure, you respect science. Riiiiiiiiiiiiiight.
