Question

Maximum force on current carrying conductor in magnetic field

A  90°

B  0°

C  180º

D  None​

Answer 1

Explanation:

A current-carrying wire feels a force in the presence of an external magnetic field. It is found to be F=BILsinθ,

where,

L is the length of the wire,

I is the current, and

θ is the angle between the current direction and the magnetic field.

As the value of sin 180 degrees is 0, the force exerted on a current-carrying wire placed in a magnetic field is zero when the angle between the wire and the direction of magnetic field is 180 degrees.

Answer 2

Answer:

A) 90•

Explanation:

The force experienced by a current-currying conductor is the maximum when the direction of current is perpendicular to the direction of the magnetic field.
