alleryThe right-hand thumb rule is also known as Maxwell's:
ACrankshaft rule
BCradle rule
CCorkscrew rule
DCrossbar rule
Answer & Solution
Correct answer: C. Corkscrew rule
1. The rule can also be pictured as driving a corkscrew.
2. Driving it in the direction of the current gives the rotation as the field direction.
3. So the rule is also called Maxwell's corkscrew rule.
