About This Product
In a tangent galvanometer the coil is set in the magnetic meridian, and a current through it deflects the compass needle by an angle whose tangent is proportional to the current. Students use it to find the horizontal component of the earth’s field, to compare currents, and to see how the number of turns changes the deflection. Schools, colleges and institutes in Trinidad and Tobago, Latvia, Democratic Republic of the Congo, Poland, Ghana and Lesotho can order the Tangent Galvanometer from Educational Instrument.
Frequently Asked Questions
Why does the Tangent Galvanometer have three coil tappings?
The 2, 50 and 500 turn tappings change the sensitivity, so both large and small currents give a readable deflection.
