Magnetism and Quantum Mechanics
Name: Sean P. M.
Does Magnetic force have Quantum characteristics? Can we
have a photon of magnetic energy? Okay I recall a photon is a
disturbance in the Electo-magnetic fields. So is magnetism a property of
Magnetism is a property of moving charges. The motion of electric charge
(as well as its spin) causes magnetic fields to occur in the space around
the charge, in circular patterns around the charge's path of motion. A
charge moving or spinning through this field experiences a magnetic force.
The same happens in reverse. One way to view things is that space
"communicates" the magnetic force between the moving charges. To have
magnetic force without electric force, you need opposite charges: one
moving fast, one moving slow. One way to do this is to have one of the
charges much more massive than the other: an atom.
