The primary origin(s) of magnetism lies in

A

atomic currents

B

Paili exclusion principle

C

polar nature of molecules

D

intrinsic spin of electron

Text Solution

Verified by Experts

The correct Answer is:
A, D
(1) An orbiting electron (atomic current) gives rise orbital magnetic moment `(vecmu_(l))`.
(4) Instrinsic spin of the electron gives rise to spin magnetic moment `(vecmu_(s))`.
Total magnetic moment of the electron, `vecmu=vecmu_(l)+vecmu_(s)`.
