Question

I'm not understanding how they are calculating Bearth. The first three are my parts and the last picture was the example they gave.

Explanation / Answer

Bearth = Bcoil / tan

Where tan = (y-length) / (x-length)

I am not able to see full graph in the first picture. You please use this formula to calculate Bearth
