How to calculate Lorentz force and Ampere force in high school physics? It's best to give a picture and explain it in detail, thank you!

F=qvBsinθ Lorentz force = charged particle charge * charged particle velocity * magnetic induction θ is the included angle between the magnetic field direction and the moving direction.

F=BILsinθ ampere force = magnetic induction intensity * current * conductor length θ is the included angle between magnetic field direction and current direction.

Judge with your left hand.
