Final answer:
Electric generator, electric transformer, and current clamp use electromagnetic induction.
Step-by-step explanation:
Electromagnetic induction is a process that generates electric current in a conductor by varying the magnetic field around it. Based on this concept, the devices that use electromagnetic induction from the given options are:
- Electric generator: It converts mechanical energy into electrical energy by rotating a magnet within a coil of wire.
- Electric transformer: It transfers electrical energy between two or more coils of wire by electromagnetic induction.
- Current clamp: It uses the principle of electromagnetic induction to measure electrical current in a conductor without physically contacting it.
