Best Answer

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.

Comment

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

Setting aside the ideas of the B-field and Lorentz force and magnetic flux, a magnetic induction unit is any device that operates on principles of magnetic induction. Let's do a bit of review. Any time an electric current flows through a conductor, a magnetic field will appear around the conductor. A changing current, and alternating current (AC), will produce a changing electromagnetic field around the conductor. If this field passes through another conductor, if it "sweeps" that other conductor, the magnetic field will induce a voltage in that conductor, and this is magnetic induction. Devices that apply this principle can be called magnetic induction units. Transformers apply this idea, and the primary windings, with their applied AC, will generate a "sweeping" magnetic field that will generate voltage in that secondary. Voltage can be stepped up or down according to the turns ratio. We have transformer action, and it is based on magnetic induction. There are other devices that apply the principle of magnetic induction, and electric motors do this. Motors are in wide use in a variety of equipments and applications.
