The primary origin(s) of magnetism lies in

Options

A. atomic currents and intrinsic spin of electrons
B. pauli exclusion principle
C. polar nature of molecules
D. electronegative nature of materials

Answer

A

Explanation

The primary origin of magnetism lies in the fact that the electrons are revolving and spinning about nucleus of an ato, which gives rise to current called atomic current.
