Monopole Magnets

Monopole Magnets

Monopole Magnets

(OP)
I was wondering if you could make a magnet monopole by shielding one side? I drew a picture to show what I mean.

Or would the flux of the south pole find a way out?

RE: Monopole Magnets

All you did with that shield is to create an easy way for the flux, if the material is magnetic. If it is non-magnetic, it won't make much difference compared to air or vacuum. Still dipole.

It may perhaps be possible to create a spherical monopole with one pole inside and the other pole on the surface of the sphere. But most flux would then be internal to the sphere and only stray flux geting out of the sphere.

RE: Monopole Magnets

Yes, you have basically just moved the south pole potential closer to the north pole.

I don't think you can create monopole with a sphere either.   If there is flux leaving the sphere surface at some location, then it must re-enter the magnet surface at some other location (to flow in a loop). One of those locations will act like north pole and one like south pole.

Sort of like a battery where the electrons continually exit but never return?

RE: Monopole Magnets

Yes, I agree.  Flux has to flow in loops just like current.  

A small confusion factor: Magnetic dipoles cannot exist.... while electric dipoles can exist (like an electron).  But that electric case is looking at charge, not current.

Just for information. .

Quote (physicsworld.com):

Ever since magnetic monopoles were first predicted by Paul Dirac in 1931, physicists have looked in vain for these elusive entities in everything from particle accelerators to Moon rocks. Now, two independent research groups claim to have caught sight of monopoles – essentially magnets with only one pole – in magnetic materials called spin ices.

RE: Monopole Magnets

Maxwell stated the principle of flux flowing in loops more formally.....  He said that the integral of flux density over a closed surface is zero  (whatever flux goes into a closed surface must exit the closed surface somewhere else).  If you had a magnetic monopole, it would seem to violate Maxwell's laws.

Dirac came later and I'm sure he was a smart guy – after all he's got a function named after him.    It must be some obscure quantum thing.    For any purpose that I know of, Maxwell's laws apply.
