A toy car ( made of soft iron ) and two bar magnets are arranged as shown in the figure. What would happen if the magnet 'A' is moved towards the car as shown in the figure. ?

Options

A. The car will not have any impact due to the motion of the magnet.
B. The car moves away from magnet A.
C. The car moves towards magnet A.
D. The car moves till it is exactly mid-way between the two magnets.

Answer

B

Explanation

Since the front part of the toy car is in contact with the south pole of a magnet B, its rear part acts as the south pole. As magnet A moves towards the rear part of the car, it should move away from magnet A due to magnetic repulsion.
Hence, the correct option is (b).
