In various learning materials a lot of right hand rules and left hand rules are introduced.
I always forget how they work exactly.
Luckily in each field where one is defined, there is a formula relating the relevant vectors with a cross product.
I you use those formulas, you only need one right hand rule.
The one that is related to the cross product.
Do you know what the cross product is?
And if so how to find the direction of the resultant vector?
