Gradient Field Generation in a Uniform Gapped Magnet

Magnets with gradient field indexed magnets usually have different gap distances in accordance with the field to be generated see Fig 1 Taking a line integral along the magnetic flux density at gap distance g with excitation current I is given by B = µ0 I /g when the permeability µ in the iron is large enough This configuration has an advantage because it needs only one set of

The effect of a magnetic field gradient on anode double layers

In experiments on anode ionization double layers in nonuniform magnetic fields it has been noted that the magnetic field gradient seems to stabilize the double layer position This effect is further investigated in a Q machine in which the magnetic field geometry could be varied We find that the position of the double layers along the axis of the device could be controlled by changing the
