When students are studying the magnetic force (which needs the right hand rule), I tell them the following: If you are right handed, put down your pencil. Oh sure, this seems silly now - but when ...

The Right Hand Thumb Rule also known as Maxwell’s Corkscrew Rule is known to determine the direction of magnetic field in relation to direction of electric current through a straight conductor.

With forefinger (magnetic field) pointing left to right, and second finger (current) pointing down, your left thumb (force) will point towards you. This is the direction in which the force acts ...
