Question

What are the factors on which the force acting on a current-carrying conductor depends when placed in a uniform magnetic field? Write the rule to find the direction of this force.

Hint:

Fleming’s Left-Hand Rule helps determine the direction of force on a current-carrying conductor in a magnetic field.

Answer 1

The force on a current-carrying conductor in a magnetic field depends on: 1. The strength of the magnetic field (\( B \)). 2. The current (\( I \)) flowing through the conductor. 3. The length (\( L \)) of the conductor in the field. 4. The angle (\( \theta \)) between the magnetic field and the conductor. The direction of this force is determined by Fleming's Left-Hand Rule: If the thumb, forefinger, and middle finger of the left hand are held perpendicular to each other, with the forefinger pointing in the direction of the magnetic field and the middle finger indicating the current, then the thumb points in the direction of the force.
