Hi, i was wondering if the right-hand rule - as in the one where your fingers are the field, the thumb is the current and the palm is the force, can only be applied to anything involving electricity or can it just be anything involving fields ?

It's applicable to any cross product in a right-handed coordinate system. It works for force because F = IL x B

When applied to motors and generators Fleming's rule uses fingers held mutually at right angles. Forefinger represents Field, seCond finger represents Current, and thuMb represents Motion. For generators you use the right hand and motors the left hand. As a memory aid say to yourself Gener(right)ers! If you have difficulty visualising the finger arrangement you can get full information by googling "Fleming's rules"
