Self and mutual induction

Mutual Induction

Mutual Induction

Whenever there is a change in the magnetic flux linked with a coil, there is also a change of flux linked with the neighbouring...
Self Induction

Self Induction

The property of a coil which enables to produce an opposing induced emf in it when the current in the coil changes is called...
Eddy Currents

Eddy Currents

When large pieces of conductors are placed in changing magnetic flux, small circulating currents are induced in them. These currents are called eddy currents...
Induced EMF and Current – Electromagnetic induction

Induced EMF and Current – Electromagnetic Induction

Whenever there is a change in the magnetic flux linked with a closed circuit an emf is produced. This emf is known as the...
Lenz’s law of Electromagnetic Induction

Lenz’s law of Electromagnetic Induction

Lenz’s law states that the polarity of the induced emf is such that it tends to produce a current which opposes the change in...
Faraday’s Laws of electromagnetic induction

Faraday’s Laws of Electromagnetic induction

Michael Faraday demonstrated the reverse effect of Oersted experiment. He explained the possibility of producing emf across the ends of a conductor when the...
