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

Measurements
Electric feld
strength is
measured in volts

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.
