Answer:
To show the force is
exerted on a current carrying conductor placed in a strong magnetic field .
Materials Required
A conducting rod (AB), connecting wires, horse shoe
magnet, battery, switch and clamp
stand.
Procedure
(i) Connect the conducting rod /6to the battery and key.
(ii) Place a strong horse shoe magnet in such a way that
the rod AB lines between the poles with magnetic field directed upwards, i.e.,
N-pole is vertically above the rod,
(iii) Plug in the key.
Observation
A current-carrying rod AB experiences a force
perpendicular to its length and the magnetic field.
Based on above observation, it can be said that when a
current carrying conductor is placed within a magnetic field, the conductor
experiences deflection. Fleming's left hand rule explains the direction of
displacement in this case. Let us assume that the current is moving in
anticlockwise direction in the loops, It that case, the magnetic field would be
in clockwise direction at the top of the loop. Moreover, it would be in
anticlockwise direction at the bottom of the loop.
