Assertion (A): Magnetism is relativistic.

Reason (R): When we move along with the charge, so that there is no motion relative to us, we find no magnetic field associated with the charge.

View answer and explanation

Correct option: A

If both (A) and (R) are true and the (R) is a correct explanation of the (A)

Option A is correct because magnetism is indeed a relativistic effect, and the reason correctly explains that the magnetic field disappears when moving with the charge.
