Question:

Case : Read the passage and answer the question(s).

A force on a charge in electric and magnetic field is given as :

F = qE + qvB

where, 

E : Electric field

B : Magnetic field

q : Charge

v : Velocity of the charge

Based on this information, answer the question that follows.

A bar magnet is made to move with a velocity v past a stationary charge q. Which of the following is true?

Options:

The magnet exerts a force on charge q

The magnetic lines of force terminate at the charge. 

The magnet does not exert any force on the charge

Magnetic monopoles do exist.

Correct Answer:

The magnet exerts a force on charge q

Explanation:

Just as moving charge exerts a force on stationary magnet, moving magnet exerts a force on stationary charge too.
