7.6
https://eng.libretexts.org
The magnetic field deep inside an ideal straight coil (Equation 7.6.3) is uniform and proportional to winding density and current.
Electromagnetic coil
https://en.wikipedia.org
An electromagnetic coil is an electrical conductor such as a wire in the shape of a coil (spiral or helix).
Helmholtz coil
https://en.wikipedia.org
A Helmholtz coil is a device for producing a region of nearly uniform magnetic field, named after the German physicist Hermann von Helmholtz.
Magnetic field due to current
https://www.bbc.co.uk
When a current flows in a wire, it creates a circular magnetic field around the wire. This magnetic field can deflect the needle of a magnetic compass.
Magnetic Field of a Circular Coil
https://physics.nyu.edu
A wire coil that is carrying a current produces a magnetic field ~B(r), where r is the distance from the center of the coil to the field point. The strength of ...
Magnetic Field Produced by a Coil
https://www.nde-ed.org
A long, straight coil of wire is called a solenoid and can be used to generate a nearly uniform magnetic field similar to that of a bar magnet.
Summary of Magnetic Field
