Discuss how a very large electric field is generated by using an induction coil

Sagot :

The working of induction coils involves principles of electromagnetic induction in which magnetic field is used to produce voltage. The magnetic field is produced by an alternating current which passes through the coil. \The induction coil has primary and secondary coils. By the principle of mutual induction, electric current is induced in the secondary coil if the magnetic flux due to the primary coil changes or it is interrupted. Small current is sent into the primary coil which creates the magnetic field. A sudden interruption of the voltage going into the primary coil causes the magnetic field to collapse abruptly. This abrupt collapse of the magnetic field generates high voltage pulses in the secondary coil by the process known as magnetic induction. The secondary coil has more turns of wire. Thus, large electric fields are produced.
