Electrons Flow in Magnetron.
12. Reaction of one magnetic field on another magnetic field.
Remember the "left-hand" rule?
The rule states that if you
point the thumb of your left hand in the direction of the electron flow,
your fingers point in the direction that the magnetic field travels around
the conductor (Figure 88).
