About This Product
Mounted with the Tube Holder D, the coils can be set in the Helmholtz geometry to give a uniform field across the tube, or arranged to produce fields aligned vertically or coaxial with the tube axis. The maximum field is approximately 10 mT, and the coils run from a 20 V power supply through 4 mm leads.
Frequently Asked Questions
Q1. Can the coils carry more than 1.0 A?
The maximum continuous current is 1.0 A. Momentary currents are rated at 1.5 A for 10 minutes or 2 A for 3 minutes.
