Draw a neat and labelled diagram of suspended coil type moving coil galvanometer. Advertisements. Solution 1. Suspended type of moving coil galvanometer:- PQRS = Rectangular coil. W = Thin phosphor bronze wire suspension. M = Plane mirror. H = Helical spring. C = Soft iron cylinder. I = Current through the coil. Solution 2.
Draw the labelled diagram of a moving coil galvanometer. Prove that in a radial magnetic field, the deflection of the coil is directly proportional to the current flowing in the coil. Solution. Verified by Toppr. Moving coil galvanometer: A galvanometer is used to detect current in circuit.
The basic principle of a moving coil galvanometer is that when a current carrying coil is placed in a magnetic field, it experiences a torque. When a current I is passed through the coil, the torque experienced is given by τ = N I A B s i n θ Where N = No. of turns of the coil, A = Area of the coil B = Magnetic field and
Moving Coil Galvanometer Construction and Diagram. The moving coil galvanometer is made up of a rectangular coil that has many turns, and it is usually made of thinly insulated or fine copper wire that is wounded on a metallic frame. The coil is free to rotate about a fixed axis.
Draw a labelled diagram of a moving coil galvanometer and explain its working. What is the function of radial magnetic field inside the coil? Solution. Verified by Toppr.
(a) Draw a labelled diagram of a moving coil galvanometer. Describe briefly its principle and working. (b) Answer the following : (i) Why is it necessary to introduce a cylindrical soft iron core inside the coil of a galvanometer. (ii) Increasing the current sensitivity of a galvanometer may not necessarily increase its voltage sensitivity.
