Induction???

Question

what is induction (in physics)? could some one please give me a detailed description? ,including the movement of electrons as well.

Answer 1

Transformers work by induction.
If you put 2 not connected wires side by side, and then put an electric current through one, it creates a magnetic field. This magnetic field induces a current in the adjacent wire.
This effect is due to induction. The causing and the induced current are both a stream of moving electrons.

Answer 2

Electrons have a negative electric charge. When they move, the electromagnetic field which surrounds them also moves, and this field will influence the movement of electrons in a conductor that is placed within this field.

The initial current in the primary of a transformer creates a moving electromagnetic field because of the current flow in the wires - if a second coil of wire is wound on this transformer, the moving field in the primary will "induce" (hence the term 'induction') a current in this wire (this is the secondary winding of the transformer).

The phenomenon is very useful in reducing or increasing the different voltages needed in modern electronic devises. Induction can also be an unintended and unwanted consequence of poor circuit design or poor wire routing - current can be induced in an adjacent wire that isn't suppose to have any - oops.

Answer 3

induction is the transfer of energy by magnetism,transfer of energy from one material to another without any contact.For example if you get close to a transmission lines that have 13.2kv you will die.You don't have to touch the cable to get shocked you will die by induction,by a magnetic feel that the current in the cable creates.
