What did Michael Faraday and Joseph Henry discover?

Expert Solution & Answer
Check Mark
To determine

To find: The discovery made by Michael Faraday and Joseph Henry.

Explanation of Solution

Introduction:

Henry discovered the property of inductance in electrical circuits and Michael Faraday discovered the electromagnetic induction.

Michael Faraday and Joseph Henry's discoveries were almost similar to each other. They discovered that by moving the magnet, electric current can be produced in a wire. During the experimentation, Henry discovery about the property of inductance in electrical circuits was first recognized on the same time in England by Michael Faraday.

Conclusion:

Henry discovered the property of inductance in electrical circuits and Michael Faraday discovered the electromagnetic induction.
