Question

What does the direction of thumb indicate in the right hand Thumb Rule in what way this is different from Fleming's left hand rule?​

Answer 1

In the right hand thumb rule, the thumb represents the direction of current and the curl of fingers represents the direction of magnetic field around the current carrying conductor.

In Fleming's left hand rule the thumb represents the direction of force experienced by a current carrying conductor placed in an external magnetic field.

Answer 2

Explanation:

The thumb indicates the direction of current in the straight conductor held by curled fingers, whereas Fleming’s left-hand rule gives the direction of force experienced by current carrying conductor placed in an external magnetic field.
