Problem the microwaves in a microwave oven are produced in, Ask an Expert

Academics

Problem: The microwaves in a microwave oven are produced in a special tube called a magnetron. The electrons orbit the magnetic field at 2.4 GHz, and as they do so they emit 2.4 GHz electromagnetic waves.

Part A. What is the magnetic field strength?

Part B. If the maximum diameter of the electron orbit before the electron hits the wall of the tube is 2.5 cm, what is the maximum electron kinetic energy?

I need help for the above question.
