What does the direction of thumb indicate in the right-hand thumb rule. In what way this rule is different from Fleming&#x2019;s left-hand rule?

Philoid · Accepted Answer

In right hand thumb rule, the direction of thumb indicates the direction of electric current and the direction of fingers wrapping shows the direction of magnetic field.

This rule is different from Fleming’s left-hand rule because Fleming left hand rule explains the effects of magnetic field on a current carrying conductor whereas Right hand thumb rule explains the magnetic field produced due to a current carrying conductor.
