Question

There was an injection of high speed electrons into a uniform magnetic field in a direction perpendicular to the magnetic field. Which of the following is correct about the interaction between the electrons and the magnetic field? a. Because the Lorentz force slows down the electrons, the speed of the electrons decreases. b. Because the electrons are injected in the direction perpendicular to the direction of the magnetic field, the magnitude of the Lorentz force is always zero. c. Because the Lorentz force accelerates the electrons, the speed of the electrons increases. d. None of the above.

Explanation / Answer
