Electric fuse is a type of over current protection device. They are engineered to contribute a negligible amount of extra resistance to the circuits they protect. This is largely accomplished by making the fuse wire as short as possible. Fuse are primarily rated as current amperes. A fuse wire of certain material and gauge will blow at a certain current no matter how long it is. Since, length is not a factor in current rating the shorter it can be made the less resistance it will have end to end.
Electromagnetic Induction is a current produced by the voltage production due to a changing magnetic field. This happens in one of the two conditions:-
When we place the conductor in a changing magnetic field.
When the conductor constantly moves in a stationary field.
