Biot-Savart law (J.B. Biot, F. Savart)
A law defines the contributions to a magnetic field through an electric current. This is analogous to Coulomb's law. Mathematically specking, it is dB = (mu0 I)/(4 pi r2) dl cross e where dl refer to the infinitesimal directed length of the electric current causing by the magnetic field, I refer to the current passing through that directed length, r refer to the distance from that directed length, & e refer to the unit vector directed from the test point to current-generating length.

It is an instrument which can detect/calculate very small electric currents. It is also called as moving magnet galvanometer. It has of three circular coils of insulated copper wir
What do you mean by transformer ratio? A current of 2A is passed through a coil of 1000 turns to produce a flux of 0.5µwb. Determine the self inductance of the coil.
An alternating voltage is triangular in shape, rising at a constant rate to a maximumof 300V in 8ms and then falling to zero at a constant rate in 4ms. The negative half cycle
