I have searched and searched but do not know what gives rise to a permanent magnet. I would like to know why two opposite forces are produced at the ends of the magnet. The closest I have got to it is to do with electron spins becoming aligned.
Help would be most appreciated
Thank you
In a theoretical perfect conductor, when it is placed into an already existing magnetic field it equally opposes the field. This is due to the induced current within it giving rise to a new magnetic field that opposes the existing one.
However when a superconductor is already in the magnetic...
Hi
From what I understand the Meissner effect occurs when a current is induced in a superconductor, from a magnet, giving rise to a magnetic field from the superconductor that opposes the magnet.
What stops the magnet from being completely repelled away from the superconductor when it is...
