A long closely wound helical coil is called a solenoid. Figure shows a section of stretched out solenoid. The magnetic field due to the solenoid…

Theory of Tangent Galvanometer: When the plane of the coil is placed parallel to the horizontal component of Earth’s magnetic induction (Bh) and a current is…

Tangent galvanometer consists of a circular coil of wire wound over a non-magnetic frame of brass or wood. The vertical frame is mounted on a…

The tangent galvanometer is a device used for measuring current. It works on the principle of tangent law. A magnetic needle suspended at a point…

Magnetic Induction along the axis of Circular Coil Carrying Current: Let consider a circular coil of radius ‘a’ with a current I as shown in…

Biot and Savart conducted many experiments to determine the factors on which the magnetic field due to current in a conductor depends. The results of…
