What happens to the force acting on current carrying conductor placed in magnetic field when :(a) Current in conductor increases. (b) Length of the conductor increase. (c) Direction of the current and magnetic field both are reversed. (d) Direction of the current is reversed without changing the direction of magnetic field.
Answers
The expression of magnetic force id defined as F = CIL Sin theta.
(a) Hence, as the current, I in the conductor increases, the force also increases.
(b) As the length of the conductor, L increases, the force on the conductor also increases proportionately.
(c) When the direction of current and magnetic field is reversed, there is no change in the direction of force as the angle, theta, is constant.
(d) When the direction of the magnetic field remains constant and the current is reversed, the direction of the force changes due to the variation of the angle, theta.
