If you point one finger in the direction of the north polarity and the other in the direction of the electrical current, your thumb will point in the direction the wire will be pulled. So in pic related, the northern pull is on the left, the current is going down, so your thumb is pointing toward you. So that's the direction of the force that's being generated.
