Object to simplify Right-hand rule

The right-hand rule is a method used in physics to determine the direction of a resulting vector in situations involving cross products, such as magnetic fields, Lorentz force, or angular momentum. It follows the convention of right-handed coordinate systems.How to apply it:Thumb: Points in the direction of the first vector (e.g., velocity or current). GreenIndex finger: Points in the direction of the second vector (e.g., magnetic field). BlueMiddle finger: Perpendicular to the other two, indicates the direction of the resulting vector (e.g., force or torque). Red(you might find other arrangements of the vectors on the fingers but the principle is always the same and the results do not change)Lorentz ForceFor a charged particle moving in a magnetic field, the force F is given by:F = q (v×B).Note: If the charge is negative, the force direction is opposite to the one given by the rule. This item is to simplify some situations where it is difficult to point fingers in the necessary direct
