Wims·hurst machine

 (wĭmz′hûrst′)
n.
An electrostatic generator used chiefly to demonstrate how static electricity is generated at high voltages, consisting of oppositely rotating mica or glass disks with metal carriers on which charges are produced by induction.

[After James Wimshurst (1832-1903), British engineer.]

Wimshurst machine

(ˈwɪmzhɜːst)
n
(General Physics) a type of electrostatic generator with two parallel insulating discs revolving in different directions, each being in contact with a thin metal wiper that produces a charge on the disc: usually used for demonstration purposes

Wims·hurst machine

(wĭmz′hûrst′)
A machine used to generate static electricity and consisting of mica or glass disks that rotate in opposite directions. The disks have metal carriers, often made of tinfoil, on which charges are produced by induction. Wimshurst machines are used to demonstrate how electric charge works.

(1) A large electrical influence machine (which produces static electricity), given by James Wimshurst in 1888, was featured in a portrait of Dewar in the collection, and apparently was still in working order and used recently prior to the refurbishment; located then in the Ante Room outside the Lecture Theatre.
It is this energy that the machine converts into a reliable constant electrical current that made it such a successful development by its inventor, James Wimshurst (1832-1903).
