## Magnetic Field inside of a Solenoid

The formula for calculating the acting magnetic field inside of a solenoid requires the values of current, in ampere and number of turns of the wire per unit length, the length being measured in meters. The value of magnetic field thus calculated is measured in Tesla.

## $$\mu ni$$

The values required are : n = number of turns per meter and i = current
