Each centre hole coil is wound on a plastic former & is provided with 4 mm socketed terminals.

The coil fits onto a double ‘C’ core, provides a suitable transformer for operation from a low voltage AC supply. In addition, it provides a useful electromagnet if used on one half of a ‘C’ core.

Used for measurement of small quantities of electrical charge.

Levelling Screws for balancing the coil. Coil with mirror suspended between long suspension at the upper end and a spring at lower end. Suspension and spring are made of phosphor bronze alloy. Bakelite case, rigid and robust. Clamping arrangement for transportation. Consistent sensitivity over a large period. Strip provided for making it a periodic
