## Homework Statement

A solenoid is designed to produce a magnetic field of 2.2 * 10^-2 t its center. It has a radius of 1.6 cm and a length of 44 cm, and the wire can carry a max current of 13 A.

The first question was what minimum number of turns per unit length must the solenoid have?

I found that to be 1350 m^-1

But the second question was what total length of wire is required?

## Homework Equations

## The Attempt at a Solution

I thought since I knew turns per unit length, current, and the magentic field that I could simply solve in reverse for this, but that's apparently not the case.

I figured that they were giving me the dimensions for something, but I'm not sure what equation to plug that into.

Any help would be greatly appreciated.
