Hi Nathan...

A MOT is built the same as most AC supplied transformers.  AC voltage in 
and an increased AC voltage out which is rectified via the diode and 
cap( for the magnetron supply hi volt) but MOTS also have a step down 
winding on them to supply the cathode voltage in the magnetron. The hi 
voltage DC is sent to the magnetron and in combination with the cathode 
an electron stream is created inside the magnetron.  The magnet 
structure ( kinda like a speaker magnet do-nut shaped) causes the 
electrons to "spiral" towards the cathode. As the electrons are 
spiraling inwards they pass by a multi bladed resonating chamber and 
they begin to create the oscillation required to  create the microwave 
energy.

hope this helped...
