Theory of Magnetic Field of a Circular Loop Current
A current passing through wire produces a magnetic field in the region around the conductor that can be calculated using Biot-Savart’s law.
When a circular loop of radius r, carrying a current I. At a point P along the axis of the coil a distance z from its center. The magnetic field circular loop formula given by:
Magnetic Field of a Circular Loop Current Principle of Work
The principle of magnetic field of a circular loop current experiment depends on studying the variation of magnetic field produced by a circular turn carrying current I, at different points along the axis of the loop.
