Answer:
C. a stationary electric charge
Explanation:
No force is exerted by a magnetic field on a stationary electric charge.
Magnetic force is given by the Lorentz equation as
F = q (v × B)
q = Amount of electric charge
v = velocity of charge
B = Magnetic flux
F = Magnetic Force
On a stationary electric charge, we know that velocity of charge is equal to zero then Magnetic force will also be zero.
