Question

How do electromagnetic induction is used in airports?

Answer 1

Almost all airport metal detectors arebased on pulse induction (PI). Typical PI systems use a coil of wire on one side of the arch as the transmitter and receiver. ... If a metal object passes through the metal detector, the pulse creates an opposite magnetic field in the object.

Answer 2

[hey,]

In fact, the same device can be used as a motor or a generator. When the device is used as a motor, a current is passed through the coil. ... An AC (alternating current) generator utilizes Faraday's law of induction, spinning a coil at a constant rate in a magnetic field to induce an oscillating emf
