Momentum of charge-magnetic coil systems
Francis R Redfern
Solenoids and toroidal solenoids exposed to an electric field have been thought to contain hidden momentum. Here I show that there is no hidden momentum in these systems.

Magnets in an electric field: hidden forces and momentum conservation
Francis Redfern
In 1967 Shockley and James addressed the situation of a magnet in an electric field. The magnet is at rest and contains electromagnetic momentum, but there was no obvious mechanica…

An alternative resolution to the Mansuripur paradox
Francis Redfern
The resolution of Mansuripur's paradox appears in numerous papers in the physics literature, preserves the Lorentz force but depends on the concept of hidden momentum. Here I propo…
