Summary
A current-carrying conductor produces a magnetic field around it. The field direction is found using right-hand thumb rule.
A conductor carrying current in a magnetic field may experience a force. This is the principle behind electric motors.
Changing magnetic field linked with a coil induces an emf. Direction follows Lenz law: the induced effect opposes the change that produced it.
Hard words & meanings
| electromagnet | Temporary magnet made using current in a coil |
| solenoid | Long coil with magnetic field like a bar magnet |
