For the purpose of deflecting electron beams in a Perrin tube, this coil produces two perpendicularly aligned magnetic fields in conjunction with the demonstration Helmholtz coils. This configuration is used, for example, to demonstrate the operation of an oscilloscope and generate Lissajous figures. Connections are via 4mm jacks. Specifications: Number of turns: 1000 DC resistance: approx. 7 Ω Load rating: max. 2 A Size: 33 x 80 mm Weight: 1 lb.
