Question

Which one out of the following is not an application of eddy currents?

• A. Transformers
• B. Speedometers
• C. Magnetic Brakes
• D. Induction furnace

Hint:

Eddy currents are beneficial in applications like magnetic brakes and induction furnaces, but unwanted in transformers, as they lead to energy loss.

Answer 1

The Correct Option is A

Eddy currents are circulating currents induced within conductors when they are exposed to changing magnetic fields. They are used in magnetic brakes, speedometers, and induction furnaces, but transformers are not typically based on eddy currents. Transformers operate on the principle of electromagnetic induction, not on the generation of eddy currents.
