## Magnetic Field Around a Wire

The formula for calculating the magnetic field around a wire requires the values of current, as measured in amperes and the distance from the center of the conductor, as measured in meters. The value thus obtained is measured in Tesla.

## $\frac{\mu i}{2\Pi r}$

The values needed are : i = current and r = distance from center of conductor
