How to calculate Lorentz force

1. Left hand rule: stretch out the left hand and let the magnetic inction wire pass through the palm (the palm is aimed at the N pole, the back of the hand is aimed at the S pole). The four fingers point to the direction of the current (that is, the direction of the positive charge movement). Then the direction of the thumb is the direction of the conctor subjected to the Lorentz force.
