What happens to catode rays when magnetic and electric fields are applied successively

Cathode rays are deflected by a magnetic field. The rays are deflected away from a negatively charged electrical field and toward a positively charge field. The charge/mass ratio for the electron is 1.8 × 108 Coulombs/gram.

Answer:
A high voltage is transmitted to the cathode ray tube, inducing the cathode to emit electrons – essentially an electrical current. ... That rule describes how a charged particle (our electron) moving in a magnetic field will be deflected by that field at a right angle to both the field and to the direction of the particle.
