Tangent galvanometer is placed at a location where horizontal component of earth's magnetic field is `B_H = 3.0 xx 10^(-5)` T. Radius of the coil used in galvanometer is 25 cm and number of turns are 100. Find the current flowing through the galvanometer if deflection is `60^@`

Text Solution

AI Generated Solution

To find the current flowing through the tangent galvanometer, we can use the relationship between the magnetic field produced by the coil and the horizontal component of the Earth's magnetic field. The formula we will use is derived from the tangent law, which states: \[ B = B_H \tan(\theta) \] Where: - \( B \) is the magnetic field due to the coil, ...
