Tangent Galvanometer
Specification:
Tangent Galvanometer -Take the Tangent Galvanometer experiment a step further!
Our
newly redesigned unit features a switchable coil selection of 100, 200,
or 400 wire turns. A built-in potentiometer and measurment taps make
taking meter readings a breeze. This self contained unit uses a single
D-cell battery, no more trying to prcisely regulate a large expensive
power supply.
Measure an electric current by determining the
magnitude and direction of the horizontal component of Earth’s magnetic
field. Set the compass needle parallel to the coil, pass an “unknown”
current through and measure the angle of deflection. Features copper
magnet wire, adjustable potentiometer; compass, and non-magnetic stand;
instructions. Needs D-cell and galvanometer or voltmeter.
