Question

if a current carrying conductor is placed perpendicular to the uniform magnetic field.what happens to the displacement of the conductor if

1.the strength of the current increases

2.if horse shoe magnet is replaced by a weak horse shoe magnet.

Answer 1

1) It will start moving with a greater acceleration as the current increases the charge moves with a greater velocity so the force given by F= q(VxB)where q is the chargeV is the velocityB is the magnetic field.2) The force will decrease as the B will decrease. 

Answer 2

1.Acceleration increases, as velocity increases.

2. Force decreases as B decreases
