Abstract : A magnetic field can act as an insulator by inhibiting the electrons from transversing a gap between two metallic plates. It is here shown that, if electrons are produced at a high enough rate on the surface of the negative plate, breakdown will occur. The 'critical' current density is given by an equation; or, if the current is space-charge limited, by another equation. The calculation here reported is non-relativistic, i.e. (H sub 0) >> (E sub 0) is assumed.
