(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A rectangular current-carrying coil, with side lengths a and b has N turns. The current, I is stable.

The coil is shorter than its width. Calculate the magnitude of the magnetic field at the centre of the rectangle.

2. Relevant equations

The law of Biot-Savart (I think).

3. The attempt at a solution

Stupid (I know) - but I am unsure of what to do with the element of Biot-Savart, which concerns the radius.

Perhaps I could divide the rectangle into 4 segments - calculate each segment:

Bsegment = (mu o/4p )(I/R)(cosa +cosb )

and then add them up?

Please, please help me as it is part of a larger assignment involving the effect of a magnetic field on a current-carrying coil.
