    This note explains the cancellations that result in a zero net magnetostatic field inside an infinitely long, thin cylindrical shell carrying a uniformly distributed current. The explanation is easily adapted for the zero net electrostatic or gravitational field inside such a shell with a uniform distribution of charge or mass respectively.
