Question

What is Helmholtz coil. Explain briefly​

Answer 1

Answer:

Helmholtz is a setup made to get a uniform magnetic field in a region.

It is constructed as:-

Two coils are taken of same geometry and placed parallel to each other at a distance of there radius.

Working:-

A uniform and equal current is passed in both coils in same direction it result in formation of magnetic field in region between coils and surprisingly the magnetic field in the region is continuous throught.

This is what Helmholtz coil is.
