Final answer:
Electric generator, electric transformer, and current clamp use electromagnetic induction.
Step-by-step explanation:
Answer:
The devices that use electromagnetic induction are:
- Electric generator: An electric generator uses electromagnetic induction to convert mechanical energy into electrical energy. It consists of a coil of wire that rotates in a magnetic field, generating an alternating current.
- Electric transformer: An electric transformer uses electromagnetic induction to change the voltage of alternating current. It consists of two coils of wire, the primary coil and the secondary coil, which are connected by a magnetic core.
- Current clamp: A current clamp uses electromagnetic induction to measure electric current in a wire without having to physically touch the wire. It consists of a coil of wire that produces a magnetic field when an electric current passes through it.
Therefore, the correct answer is (d) All of the above.
