- When current is passed throgh a galvanometer, the coil oscillates about its mean position before it comes to rest.
- To bring the coil to rest immediately, the coil is wound on a metallic frame.
- Now, when the coil oscillate, eddy currents areset up in the metallic frame, which opposes further oscillations of the coil.
- This inturn enables the coil to attain its equilibrium position almost instantly.
- Since the oscillation of the coil die out instantaneously, the galvanometer is called dead beat galvanometer.

Why tangent galvanometer is called tangent galvanometer?
because in tangent galvanometer earth magnetic field and magnetic field of magnet inside galvanometer are perpendicular to each other
How you convert galvanometer into ammeter in detail?
By attaching a resistance in parallel connection with the galvanometer. Or when a low resistor connected in parallel with galvanometer ,the galvanometer is converted in ammeter. and the resistor is called shunt resistance.
What is weston galvanometer?
The weston type galvanometer is a moving coil galvanometer in which a pointer is attached to the coil for measuring deflection due to torque .
Steps in making a galvanometer?
A galvanometer is used to test an electrical current. A galvanometer can be made using a compass and a thin gauge of wire.
