Question

A force is excreted on the current carrying conductor. The direction of this force

depends on both the direction of the current and the direction of the magnetic field.

This force is maximum when the direction of current is perpendicular to the direction

of the magnetic field.

a) By which law we can determine the direction of force excreted on the current

carrying conductor.

b) In which electrical equipment this principle is used.

c) Draw a diagram representing construction of this equipment.

d) Write the working of this equipment in brief.​

Answer 1

A) Flemmings left hand rule

Index finger indicates the direction of magnetic flux and the middle finger indicates the direction of current, then the thumb will give the direction of force

B) electric motor
(converts electrical energy into mechanical energy)
