The right-hand rule I use is as follows: For A→×B→=C→ Lay the side of your palm on the table for A, curl your fingers in the direction of B, and your thumb will point in the direction of C. For the case of F→/I=ℓ→×B→ The side of your palm is in the direction of the current, your fingers curl in the direction of the B-field, and the force is given by the direction of the thumb.
