Hi Malcolm and all,

Here is part of an abstract from the paper

"Scalar potential developed by a spinning current-carrying solenoid" by 
Joseph Tate, 1974. The experiment described here measured an induced charge 
using an electrometer using two 5886 vacuum tubes and an HP 412-A 
millivoltmeter.

 

"O'Rahilly, 
Electromagnetics(1938) conducted a theoretical analysis of the 
electric field about a spinning current-carrying coil. He conducted 2 analyses, 
one based on equations developed by Lorentz and the other on equations developed 
by Ritz. Both studies showed that currents in the spinning coil would generate 
electric fields which produced forces on stationary charges. The two theories 
were in disagreement on the value of electric field."
