Question

.How is a large induced electric current obtained in a loop?

plz ans this fast​

Answer 1

An electric current can be induced in a loop by a changing magnetic field. This would be the current in the secondary circuit of this experimental set-up. The induced current exists only while the magnetic field through the loop is changing..

Answer 2

Answer:

An electric current can be induced in a loop by a changing magnetic field. ... The induced current exists only while the magnetic field through the loop is changing. This is generally expressed as: an induced emf is produced in the loop by the changing. magnetic field.
