单词 Lorentz force
释义
Lorentz force

Physics
  • The force exerted on a moving electric charge by a magnetic field. The force F exerted on a charge Q which is moving with a velocity v by a magnetic field with magnetic flux density B is given by the vector product: F=Q(v×B).


Electronics and Electrical Engineering
  • The force experienced by an electron or other charged particle moving in a region of electric field, E, and magnetic flux density, B. The force due to the magnetic flux acts in a direction that is perpendicular both to the direction of particle motion and of the flux density and is given by the vector product qv×B, where v is the particle velocity and q the charge. The total force due to both fields is given by F=qE+qv×B.
