Part A The microwaves in a microwave oven are produced in a special tube called a magnetron. The electrons orbit in a magnetic field of 8.7×10-2 T at a frequency of 2.4 GHz, and as they do so they emit 2.4 GHz electromagnetic waves. If the maximum diameter of the electron orbit before the electron hits the wall of the tube is 2.3 cm, what is the maximum velocity the electrons may have?

Ferromagnetism

Ferromagnetism is a mechanism by which some materials show magnetic properties. Iron and magnetite, an oxide of iron, are two naturally occurring materials that show the property of ferromagnetism. The word ferromagnetism is derived from the Latin name of iron, "Ferrum" as it was the first observed material to show such property. The property of ferromagnetism is shown by only a few substances such as iron, nickel, cobalt, and their alloys. Some transition metals and alloys of rare-earth metals also show ferromagnetism.
