Question

A stationary positive charge, q, is located in a magnetic field, b, which is directed toward the right. what is the direction of the magnetic force on q?

Answer 1

There is no magnetic force on the charge. Magnetic force will only be on the charge when the charge is in motion.Because, mangetic forec, F = q(v×B)

where v = velocity of charge particle.
B is magnetic field
v is the velocity of charge.

Since the velocity of charge is zero, Thus, F will be zero. So, there is no magnetic force.
