The right hand rule is a common mnemonic for understanding orientation of axes in 3D space.

One use of the rule is for understanding direction in Physics, specifically Magnetism.

Using the rule, a student can figure out the direction of magnetic fields (B), current (I), charge (Q), and force (F).

There are three variations of the rule and a special case, each with a different purpose.

RHR #1 - Determining the direction of a magnetic field given current

RHR #2 - Determining the direction of force given current and a magnetic field

RHR #3 - Determining the direction of a force given charge and a magnetic field

RHR #4 (unofficial) - Determining the direction of current as a result of a change in magnetic flux
