Magnetic Field of a Solenoid

Claimed by ramin8 !!

A Solenoid is a type of electromagnet, which consists of a coil tightly wound into a helix. Usually it produces a uniform magnetic field when an electric current is run through it. The purpose of a solenoid is to create a controlled magnetic field.

The Main Idea

The purpose of this application is to explore another way to apply the Biot-Sarvart law. The magnetic field is uniform along the axis of the solenoid, when electric current is run through it. The solenoid has has to have coils much larger than the radius.

A Mathematical Model

This is the formula for the magnetic field inside a long solenoid: [math]\displaystyle{ B = \frac{\mu _{0}\cdot \frac{NI }{L} }[/math]
