Electromagnetic induction is the process of inducing electric current in a coil with the help of a magnet.

Whenever a conductor is moved through a magnetic field, or the magnetic field fluctuates in strength (as with an AC electromagnet), a current will be induced in that conductor. Induction cooktops work by passing a large AC current through a conductor under the cooktop, creating a fluctuating magnetic field which induces an electric current through the cookware - heating the cookware by electrical resistance.

The process by which a substance, such as iron or steel, becomes magnetized by a magnetic field. The induced magnetism is produced by the force of the field radiating from the poles of a magnet.


Further to the original answer, it is a voltage that is induced into a conductor, NOT a current.

if there is no magnetic induction there will be no electricity

Magnetic induction and electromagnetic induction are used pretty much interchangably. Magnetic induction is really electromagnetic induction. One of the four fundamental forces in the universe is the electromagnetic force. Not the electrical force or the magnetic force, but the electromagnetic force. And magnetic induction is just another term for electromagnetic induction.

actually magnetic field is the region around magnet and magnetic induction is the process of using magnetic field to produce current , voltage etc'magnetic induction is basically force per unit length and current. from [fatima ]

Induction, which refers to induced voltage is related to magnetic field and area. Change of magnetic flux inside a wire loop caused a voltage to be induced or induction. A change in magnetic field or area changes the value of induction. Induction can also be considered a function of the current change rate.
