Question

Uses a Chuck and follows Faradays law

		Electric Razor
		Garbage Disposal
		An Electric Drill
		A Water pik

Answer 1

Faraday formulated two laws of electromagnetic induction which are as follows:

1. First law : Whenever a conductor is placed in a varying magnetic field, an electromotive force (EMF) is induced.

2. Second law : The induced EMF is equal to the rate of change of flux.

These two laws govern the motion of an electric motor.

In the given question, all the devices use an electric motor (in one form or the other) and hence follow Faraday's law.

It is also given that the device, which we need to choose, also uses a chuck.

A chuck is a special type of clamp used to hold cylindrical objects.

In electric drills, the drill bit (part that rotates and makes holes) is attached to the drill using a chuck.

Therefore, an electric drill is a device that uses both chuck and Faraday's Law.
