ELECTRO MAGNETIC INDUCTION:
Electromagnetism is the relation between magnetism and electricity Faraday's discovery of electromagnetic induction had made more impact on our world than any other scientific discovery.
Using this principle main machines are built to generate a large quantities of electricity has opening the way for everything for electric lightening to telecommunications .
Important points : (to be remembered)
⏩A conductor carrying current produces a magnetic field around it this effect of electric current is known as the magnetic effect of the electric current
⏩When a magnetic field linked with a circuit changes and electromotive force will be induced in the circuit this phenomenon is called as electromagnetic induction
⏩ Factorsinfluencing induced electromotive forces are the
1) Number of turns of the coil
2)Strength of the magnetic field
3) The speed with which the magnet or the coil most
4) Area of the coil

When electric current is passed through a conductor, a magnetic field is produced around the conducter. According to Faraday, whenever there is a change in the magnetic line of force associated with a conductor, an electromotive force (e.m.f.) is set up at the ends of the conductor which lasts as long as the change is taking place. Thus phenomenon is termed as electromagnetic induction.
