Question

Why does a current carrying conductor experiences a force when it is placed in a magnetic field? State Flemming's left hand rule.

Answer 1

The drifting of free electrons of a conductor in definite direction causes the current to flow through it. When such a conductor is placed in a uniform magnetic field each drifted electron of conductor experience a magnetic force. this magnetic force is collectively experienced by the conductor as whole. Thus it experiences a force .
Fleming’s left hand rule
Stretch the thumb finger,index finger and the middle finger of your left hand perpendicular to each other.when the middle finger is in the direction of current and forefinger is in the direction of magnetic field then thumb will indicate the force experienced by conductor.
For easy understanding
(C)enter finger - (C)urrent
(F)orefinger-(F)ield
(T)humb finger-(T)hrust

Answer 2

Why does a current carrying conductor experiences a force when it is placed in a magnetic field?

When a current-carrying conductor is placed in a magnetic field the wire experiences a force due to the interaction between the field and the magnetic field produced by the moving charges in the wire.

• That is why the conductor experiences a force.
