<p>Anyone mind explaining it to me. I kno its an easy concept, but its kind complicated when it involves magnetic flux.</p>
<p>There are 2. For current, thumb points in direction of current, curl you fingers in the direction of the magnetic field. Like you are putting in a screw. The other one is for like forces and its to show what A X B (A cross B) is and A = idex finger point, Three fingers go in direction of B, and your thumb points in the direction of the force. If q= -e then the force is opposite the diection of the thumb. This is also used in angular momentum R X mV</p>
<p>thanks. that helped</p>
