## Electric Lines of Force or Field Lines and Properties

Dear Friends, it is very important to discuss the concept of electric lines of force or commonly known as field lines also as these will

## What is magnetic flux and its units

Hello friends, last time we have discussed about electric flux and its units. Similarly in magnetism, there is concept of magnetic flux. Have you imagined,

## What is electric flux and its units

To understand the meaning of electric flux, let us first understand the meaning of flux. Flux: Flux simply means the flow. For example if we

## Electromagnetic waves and their features

Q: How the electromagnetic waves are produced? Ans: We know that a charge at rest produces an electric field around it but no magnetic field

## More characteristics or properties of transverse electric and magnetic waves in parallel planes

Last time I have discussed the few characteristics or properties of transverse electric and magnetic waves in parallel planes. Let us discuss more properties of

## CHARACTERISTICS OF TRANSVERSE ELECTRIC AND TRANSVERSE ELECTRIC WAVES

The characteristics or properties of transverse electric (TE) and transverse magnetic (TM) in parallel planes or plates waves can be studied with the help of

## Transverse magnetic waves in parallel planes

DEFINITION TRANSVERSE MAGNETIC (TM) WAVES OR E WAVES   : In this case, the component of magnetic field vector H lies in the plane transverse to

## Transverse electric waves

DEFINITION TRANSVERSE ELECTRIC (TE) WAVES OR H WAVES IN PARALLEL PLANES: In the case, the component of electric field vector E lies in the plane

## Waves between parallel planes

Let us discuss how waves propagate through parallel planes and derive the necessary relation of transverse electric and magnetic waves: Assumptions : (a)  Pair of

## Poynting theorem and derivation

Poynting Theorem Statement. This theorem states that the cross product of electric field vector, E and magnetic field vector, H at any point is a
