Question

A straight current carrying conductor is placed inside a uniform magnetic
field. The force per unit length acting on the conductor is

(A) maximum when the conductor is perpendicular to the direction of
magnetic field.
(B) maximum when the conductor is along the direction of magnetic
field.
(C) minimum when the conductor is perpendicular to the direction of
magnetic field.
(D) minimum when the conductor makes an angle of 45° with the
direction of magnetic field.
​

Answer 1

Answer:

A current carrying conductor placed in a magnetic field experiences a force. If the direction of the field and that of current are mutually perpendicular to each other, then the force acting on the conductor will be perpendicular to both and that can be determined using the Fleming's left-hand rule.

(A) maximum when the conductor is perpendicular to the direction of

magnetic field.

Answer 2

The force per unit length acting on the conductor is maximum when the conductor is perpendicular to the direction of the magnetic field (A).

Explanation:

• When a current carrying conductor is placed on a uniform magnetic field, it will experience a force and this force will be perpendicular if the conductor is placed perpendicular to the direction of the magnetic field.
• In addition to this, the force exerted will be both perpendicular to the conductor as well as the magnetic field as per the Fleming's rule.
