Please answers this question fast guys physics class 7 ​

Answer 1

Answer:

1. Miniature Circuit Breakers (MCBs) are electromechanical devices which are used to protect an electrical circuit from an overcurrent. The lead reasons for an overcurrent could be a short circuit or overload. Unlike a Fuse, MCB does not have to be replaced every time after a fault occurs and it can be reused.

2.An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. Electromagnets usually consist of wire wound into a coil. A current through the wire creates a magnetic field which is concentrated in the hole, denoting the centre of the coil.
