e resistance R and the bobbin B in-versely proportional to their resistances. Therefore, whena large current is passing through H, d oorrespomdiriglyiarge current is passing thrmigh bobbin B.

The attraction of the solenoid is balancedby a spring or gravity and the position at which equilibriumoccurs is a measure of the attracting force, and therefore ameasure of the ampere turns in the solenoid. Whether theposition of the pointer is to be read off as volts or…
