A magnetron differs from a conventional diode tube in that it uses a
permanent magnet to deflect the electron beam and its plate is at
ground potential. The reason for grounding the plate is to
a.
prevent shock hazards.
b.
reduce magnetron pushing.
c.
permit the use of a conventional filament transformer for the
magnetron.
d.
reduce the strength of the electric field required for proper
operation.
14.
The combination of the electric and magnetic fields causes the
electrons to take a twisting spiraling motion toward the anode.
The
magnetron that has the greatest magnetic field strength is represented
in Figure 103 in the sketch labeled
a.
