Question

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.

What is the magnetic field strength?

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?

The magnetic field strength is 0.086 T

The maximum kinetic energy is J

Explanation:

Given:

Frequency Hz

(A)

The magnetic field related to cyclotron is given by,

Where mass of electron kg, C

T

Therefore, the magnetic field strength is 0.086 T

(B)

Diameter of orbit m

The maximum kinetic energy is given by,

KE =

Where

KE =

KE =

KE = J

Therefore, the maximum kinetic energy is J
