12.9
https://phys.libretexts.org
The magnetic field strength at the center of a circular loop is given by B=μ0I2R (at center of loop),, where R is the radius of the loop. RHR-2 ...
22.9 Magnetic Fields Produced by Currents
https://pressbooks.bccampus.ca
This equation becomes B=μ0nI/(2R) B = μ 0 n I / ( 2 R ) for a flat coil of N N loops. RHR-2 gives the direction of the field about the loop. A long coil is ...
