Electromagnetic Induction

Notes

Magnetic Flux

Magnetic flux \((\phi \) through any surface is defined as the number of magnetic lines of force passing through an area normally. This note provides us an information on magnetic flux.

Flux Linkages and Faraday’s Law of Electromagnetic Induction

The product of number of turns (N) of the coil and magnetic flux linking the coil is called flux linkages. This note provides us an information on flux linkages and Faraday’s law of electromagnetic induction.

Direction of Induced e.m.f and Current

According to Faraday's law , e.m.f depends on the number of turns N and rate of change of magnetic flux. This note provides us an information on direction of Induced e.m.f and current.

AC Generator or AC Dynamo

An electrical machine used to convert mechanical energy into electrical energy is called A.C. generator. This note provides us an information on AC generator or Dynamo.

DC Generator or DC Dynamo

D.C. generator is a device which converts mechanical energy into electrical energy. This note provides us an information on DC generator or DC dynamo.

Self Inductance

Self inductance is the property of a coil by virtue of which it opposes the growth or decay of the current flowing through it. This note provides us an information on self inductance.

Mutual Induction

Mutual induction is the phenomenon of inducing e.m.f in a coil due to rate of change of current or change in magnetic flux linked with nearby coil. This note provides us an information on mutual induction.

Induced Electric Fields and Energy Stored in an Inductor

The electric field in the loop is not conservative because line integral of \(\vec E\) around a closed path is not zero. This note provides us an information on induced electric fields and energy stored in an inductor.
