Lorentz force in Science
Lorentz force  
The total force exerted on a charged particle by electric and magnetic fields. All charged particles encounter a force from an electric field, oriented in the direction of the field (or the opposite direction, depending on the sign of the charge), while moving charged particles also encounter a force oriented at a right angle to both the direction of motion and the magnetic field. The Lorentz force is the driving force in electromagnets and is responsible for the Hall effect. The Lorentz force is named for Henrik Lorentz. See also electromagnetism.
