Question

A current carrying conductor placed in a magnetic field experiences a force. The displacement of the conductor in the magnetic field can be increased by ?

Answer 1

Hint:In a magnetic field, a moving charge encounters a force that is perpendicular to both its own velocity and the magnetic field. When the direction of the current is perpendicular to the direction of the magnetic field, the conductor's displacement is greatest.

Complete answer:
Free electrons move with a drift velocity in a current carrying conductor and feel magnetic force, but positive ions are stationary and do not feel magnetic force. As a result, there is no net charge on the current carrying conductor. The amount of force a current carrying conductor experiences in a magnetic field is determined by
(a) current in the conductor.
(b) strength of the magnetic field.
(c) By increasing the magnetic field, the direction of the current with respect to the magnetic field and its displacement can be increased.

Hence, the displacement of the conductor in the magnetic field can be increased by increasing the magnetic field.

Additional Information:
When current flows through a conductor, it acts as a temporary magnet due to its magnetic effect; this type of magnet is known as an electromagnet, and an electric motor is used to generate torque due to the current in the magnetic field. Because of the current, the bulb generates heat.

Note:Magnetic influence of current refers to the fact that current flowing through a wire produces a magnetic field around it. Hans Christian Oersted discovered the magnetic effect of current and observed that a current-carrying wire might deflect a magnetic needle.
