Answer:
C direction
Step-by-step explanation:
Reversing the direction of the flow of electric current in a wire coil reverses an electromagnet's north and south poles.
Every time the north and south poles is exchanged, the direction of flow of electric current in a w ire reverses.
- An electromagnet is a form of magnet in which the magnetic effect is produced by the movement of electric current in wire.
- A coil of wire wound round and connected to an electric source will produce an electromagnet.
- When we change the direction of flow of the current the polarity of the poles will also change.
