Right Hand Rule.

To execute the right hand rule, all you need is your right hand, and your voice - so you can meow.

Right Hand Rule #1 (for conductors):

Take your right hand, and point the thumb in the direction of the current (I) flow. The current will be travelling in a conventional current, meaning from positive to negative. Now meow and curl your fist. The direction of the fingers is the direction of the magnetic field (B) around the conductor, as seen in the diagram below.

Right Hand Rule #2 (for coils):

Once again, take your right hand, meow, then grasp the coil so that the fingers are curved in the direction of the current (I). The thumb points in the direction of the magnetic field within the coil and represents the north (N) end of the electromagnet produced by the coil. Take a look at the diagram below!
