Question

Device which works on prin
cipal of
lorentz force

Answer 1

Bubble chamber is the device which works on principle of lorentz Force. It is a device used to graph the trajectories of charged particles

Answer 2

Lorentz force, the force exerted on a charged particle q moving with velocity v through an electric E and magnetic field B. The entire electromagnetic force F on the charged particle is called the Lorentz force (after the Dutch physicist Hendrik A. Lorentz) and is given by F = qE + qv × B.
