Ways to Change flux| Area

The electric displacement current through a surface area "S" is proportional to the Magnetic flux through S. Rate of change of magnetic flux through S Electric flux through S, Rate of change of electric flux through S

In a coil of resistance 100 Omega , a current is induced by changing the magnetic flux through it as shown in the figure. The magnitude of change in flux through the coil is

Some magnetic flux is changed from a coil of resitance 10 Omega . As a result, an induced current is developed it, which varies with time as shown in Fig. 3.213. Find the magnitude of the change in flux through ythe coil in weber.

STATEMENT - 1 : Whenever there is a change in flux linked with a coil in a circuit, an induced current is set up in it. and STATEMENT - 2 : Whenever there is a change in flux linked with a coil in a circuit, an induced emf is set up in it.

An electric current can he induced in a coil by flux change produced by another coil in its vicinity or flux change produced by the same coil. In both cases, the flux through a coil is

The circulating induced current produced in a metal plate due to the change in magnetic flux are

When is the magnetic flux through an area element (i) maximum (ii) zero ?
