Electromagnetic induction

What is electromagnetic induction?

Electromagnetic induction is the process of generating an electric current from a changing magnetic field.

What are Fleming's Left-Hand Rule and Right-Hand Rule?

Fleming's Left-Hand Rule is used for electric motors; it states that if the thumb, index, and middle finger of the left hand are held mutually perpendicular, the thumb represents force (motion), the index finger represents the magnetic field, and the middle finger represents the current. Fleming's Right-Hand Rule applies to generators; here, the arrangement is the same, but the thumb represents the induced current.

What is the function of AC motors?

AC motors convert alternating current electrical energy into mechanical energy.

What is the function of DC motors?

DC motors convert direct current electrical energy into mechanical energy, typically running on a fixed voltage.

What is a generator?

A generator is a device that converts mechanical energy into electrical energy through electromagnetic induction.

What is the difference between AC and DC generators?

AC generators produce alternating current, while DC generators produce direct current.
