A current-carrying solenoid behaves like which of the following?
AA horseshoe magnet
BA bar magnet
CA point charge
DA capacitor
Answer & Solution
Correct answer: B. A bar magnet
1. A solenoid is a coil of insulated wire with many turns.
2. When current flows, each turn produces a circular magnetic field.
3. The combined field is uniform inside and looks like a bar magnet outside.
4. One end of the solenoid acts as the north pole, the other as the south.
5. So a current-carrying solenoid behaves like a bar magnet.
6. Horseshoe magnets have a U-shape and bend their field differently.
