Question

The force experienced by a current carrying conductor placed in a magnetic field is largest when the angle between the direction of current and magnetic field is a) 45° b) 60° c) 90° d) 180°

Answer 1

Answer:

c)90°

Explanation:

The force on a charged particle moving in a magnetic field is at its maximum when the particle is moving at right angles to the direction of the magnetic field and zero when the particle is moving parallel to the field. The direction of the drift velocity of electrons in a conductor is along the length of the conductor. Thus, the magnitude of the force on a current-carrying conductor in a magnetic field varies with the angle between the direction of the length of the conductor and the direction of the magnetic field.

Hence, The magnitude of force is at a maximum when the angle between the conductor and the magnetic field is 90 degrees, that is, when the direction of current in the conductor is perpendicular to the magnetic field.
