Hi! Can anyone please tell me where this equation was derived from?
This equation is used to get the magnetic field (B).
I is current and r is the distance. And I think I understand the Meu. And yet I have no idea where the 2pi came from. I looked in my textbook, internet and asked friends but nobody seems to know.
Thank you!
