When the magnetic flux associated with a coil changes an emf is induced in the circuit.
When an electrical appliance is switched off, sparking occurs, Why?

When the magnetic flux associated with a coil changes an emf is induced in the circuit. State Faraday.s law of electromagnetic induction

When the magnetic flux associated with a coil changes an emf is induced in the circuit. Mention the physical significance of Lenz.s law with an example.

Michael Faraday observed that whenever magnetic flux linked with a coil changes, an e.m.f. is induced in the coil. Suppose a coil of .N. tums and radius .R. is kept normal to a varying magnetic field B = BoCos omega t. Obtain the e.m.f. induced in the coil.

Michael Faraday observed that whenever magnetic flux linked with a coil changes, an e.m.f. is induced in the coil. Suppose a coil of .N. tums and radius .R. is kept normal to a varying magnetic field B = BoCos omega t. What is the flux linked with the coil at any instant t?

The generation of emf when the magnetic flux asso ciated with a coil changes is known as electromagnetic induction. Calculate the energy stored in an inductor of in ductance 50mH when a current of 2 A is passing through it.

The generation of emf when the magnetic flux associated with a coil changes Is known as electromagnetic Induction:- Mention the factors on which the self Inductance of a solenoid depends.
