Question

what is the reason for induced electricity in a coil when electricity is passed in second coil. ​

Answer 1

Answer:

Because of the large number of turns in the secondary coil, the secondary voltage pulse is typically many thousands of volts. This voltage is often sufficient to cause an electric spark, to jump across an air gap (G) separating the secondary's output terminals. For this reason, induction coils were called spark coils.
