Right Hand Rule#1&2

Right-Hand Rule #1 (RHR #1)
Right-Hand Rule #1 determines the directions of magnetic force, conventional current and the magnetic field.  Given any two of theses, the third can be found.
 

Using your right-hand: point your index finger in the direction of the charge's velocity, v, (recall conventional current). Point your middle finger in the direction of the magnetic field, B. Your thumb now points in the direction of the magnetic force, Fmagnetic.

Right-Hand Rule #2 (RHR #2)
Right-Hand Rule #2 determines the direction of the magnetic field around a current-carrying wire and vice-versa

Using your right-hand:

Curl your fingers into a half-circle around the wire, they point in the direction of the magnetic field, B
Point your thumb in the direction of the conventional current.
