Defnition

Anelectric feld

is a force eld

surrounding

electric charges or

group of charges

where a force acts

on charges within

A magnetic feld

is a region of

magnetic inuence

around the

magnetic poles and

moving charged

particles.

Generation

An electric feld

occurs wherever a

voltage is present.

Electric elds are

created around

appliances and

wires wherever a

voltage exists.

Magnetic felds

are created

whenever there is

a ow of electric

current.

Force

The force of an

electric feld is

proportional to the

electric charge.

The higher the

voltage, the

stronger the

electric eld

The force of a

magnetic feld is

proportional to the

charge and the

speed of electric

charge.

As the amount of

current owing

Force

An electric feld isthe force per unit

charge

experienced by a

non-moving point

charge at anygiven location

within the eld.

A magnetic feldis detected by the

force it exerts on

other magnetic

particles and

moving electriccharges.

Their relationship can be clearly

explained with the help of Maxwells

Magnetic fields are

measured in

milliGauss (mG).

A gaussmeteris

used in measuring

magnetic fields.

Movement in ElectromagneticField

An electric feld

moves

perpendicular tothe magnetic eld.

A magnetic feld

moves

perpendicular tothe electric eld.

The directions in which they move are

perpendicular to each other.
