# Lorentzs Force 3D

Direction of the Lorentz force

Conductors in which current flows in a magnetic field, are forced to move. The direction of this force is perpendicular to the current and the magnetic field respectively.

More precisely, we can find out below.
1. Let’s open your right hand.
2. Match the direction of your fingers with the direction of the magnetic field.
3. Match your thumb with the direction of the current.
4. At this time, the direction from the palm of the hand is the direction of the force.

The strength of the Lorentz force

Lorentz force is proportional to the strength of the current and the surrounding magnetic field.If the direction of the current is perpendicular to the magnetic field, it is the strongest. If the direction of the current is parallel to the magnetic field, the Lorentz force is zero.
