A magnetic field exerts no force on:
(a) an electrical charge moving perpendicular to its direction (b) an unmagnetised iron bar
(c) a stationary electric charge (d) a magnet

Academic Physics NCERT Class 10

(c) a stationary electric charge

Explanation

Magnetic force is given by Lorentz equation as:

F = q (v × B)

Here, q = amount of electric charge,

v = velocity of charge and

B = magnetic flux

So, when velocity of charge (v) = 0, then magnetic force (F) = 0.
