Question

27. Explain Fleming's Left-Hand thumb rule. When is the force exerted on a current carrying conductor
(1) Maximum and (ii) Minimum?​

Answer 1

Answer:

Fleming’s Left Hand Rule It is found that whenever a current carrying conductor is placed inside a magnetic field, a force acts on the conductor, in a direction perpendicular to both the directions of the current and the magnetic field.

Answer 2

Answer with Explanation:

Fleming's Left-Hand thumb rule :

According to this rule, stretch the thumb,  forefinger and middle finger of your left hand  such that they are mutually perpendicular . If the first finger points in the  direction of magnetic field and the second  finger in the direction of current, then the  thumb will point in the direction of motion or  the force acting on the conductor.

The force exerted on a current carrying conductor is maximum when the direction of current in the conductor is perpendicular to the magnetic field or the angle between direction of current and magnetic field is 90°.

The force exerted on a current carrying conductor is minimum when the  the angle between direction of current and magnetic field is 0°.
