What is the rule for determining the direction of the Lorentz force?

Determination of the direction of the Lorentz force: if you position your left hand so that the component of the magnetic induction vector perpendicular to the particle velocity vector enters the palm, four fingers indicate the direction of motion of a positively charged particle, then the direction of the Lorentz force will coincide with the direction of the thumb bent 90 degrees.

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
