DIRECTIONS: Read the passage given below and answer the questions that follow. Passage When an electric current passes through a wire, it behaves like a magnet. This is the magnetic effect of current. When the electric current is switched off, the coil generally loses magnetism. Such coils are called electromagnets. Look at the following diagram and tell if compass needle placed near the connecting wire will show deflection when the switch in the circuit is in 'ON' position?

A) It will show deflection

B) It will not show deflection

C) Sometimes it will show deflection and sometimes it will not show any deflection

D) None of the above is correct.
