What is the difference between magnetism and electromagnetism?
Magnetism is produced naturally but electro magnetism is
produced by passing electric current through a substance...
Answer2: The difference between magnetism and electromagnetism
is the constants c, the Relativity Constant and z the Quantum
Constant. z is the free space resistance to the electromagnetic
wave.375 oh, z= h/Q2. Q is the Photon Charge and h is Planck's
The magnetic and electromagnetic fields are related by c and
E = cB = zH = zcD.
