Text Solution

Verified by Experts

We often come across a metal detector at an airport. Walking through a metal detector is walking through a coil of wire that carries a small electric current and is associated with some magnetic field. If you are carrying some metal like iron, you change the magnetic field. This induces change in current in the coil of the metal detector. The detection of this change sets p an alarm.
