The galvanometer is oriented so that the plane of the coil is vertical and aligned along parallel to the horizontal component He of the Earth's magnetic field (i.e. parallel to the local "magnetic meridian"). When an electrical current flow through the galvanometer coil, a second magnetic field H is created. At the center of the coil, where the compass needle is located, the coil's field is perpendicular to the plane of the coil. These two perpendicular magnetic fields add vertically, and the compass needle points along the direction of their resultant He + H. The current in the coil causes the compass needle to rotate by an angle\ \theta.

Why tangent galvanometer is called tangent galvanometer?
A tangent galvanometer is called so because it uses the tangent of the angle through which a magnetic needle is deflected to measure electric current. The horizontal component of the Earth’s magnetic field and a coil carrying current creates a magnetic field that deflects the needle, making it tangent to the circle of the coil.
What is the use of Tangent Galvanometer?
A Tangent Galvanometer is used to measure small electric currents in a circuit. It works on the principle of the tangent law of magnetism, where the magnetic needle aligns with the magnetic field produced by the current passing through a coil. This alignment allows for the measurement of the current based on the angle of deflection of the needle.
How tangent galvanometer is used to determine the horizontal component of earth's magnetic field?
by using the formula b=μn/2A(I/TAN Ɵ)....where μ=4πx10 pow(-7)n=number f turns of the coilA=radius of the coil(m)I=current flowing through the coil(A)Ɵ=angle of deflection in the tangent galvanometer.
How do you study earth's magnetic field using a tangent galvanometer?
The expression for tan @ is F/B Here F = mu not n I / 2a mu not = permiability of air which equals to 4pi x 10-7 H/m n = number of turn in the TG a - radius of coil in TG in meter I = the current flowing through in ampere B is the earth's magnetic field. Hence B = F / tan@ Here @ is the angle of deflection in the TG when two perpendicular fields are applied. Here one is earth's magnetic field whose induction is B tesla and F is the magnetic field produced due to flow of current in the TG coil

What is reduction factor of tangent galvanometer?
The reduction factor of a tangent galvanometer is the ratio of the tangent of the angle of deflection produced by a given current to the actual value of that current. It is used to calibrate the instrument so that the deflection angle can be directly related to the current flowing through it.

What are applications of ballistic galvanometer?
Ballistic galvanometers are used in applications where a very short-duration current measurement is required, such as measuring the charge of particles in particle physics experiments or determining the output of pulsed power supplies. They are also used in high-speed photography to capture events that occur in a very short period of time.
