TANGENT GALVANOMETER, Physics practical std 11 & 12 GSEB

Tangent Galvanometer

TANGENT GALVANOMETER, 

AIM :

To determine the value of H with the help of a tangent galvanometer.

APPARATUS :

A tangent galvanometer, an ammeter, a battery, a simple key, a rheostat, a reversible key and a spirit level.

PRECAUTIONS

1)      Keep the tangent galvanometer away from an ammeter.

2)       The circular platform must be properly leveled horizontally.

3)       Before taking the reading of the pointer of a tangent galvanometer, the sight should be so adjusted that the pointer and its image in the mirror, become collinear.

4)       The rheostat should be so adjusted that the deflection is between 30⁰ and 60⁰.

5)       The coil of the tangent galvanometer should be adjusted parallel to the magnetic field of the earth.
