L> Magnetic field of a present Loop
Magnetic field of current Loop evaluating the direction of the magnetic field developed by a current-carrying segment of wire mirrors that all components of the loop contribute magnetic field in the exact same direction within the loop. | |
Electric present in a circular loop create a magnetic field which is an ext concentrated in the center of the loop than outside the loop. Stacking many loops concentrates the field even more into what is called a solenoid. | |

At a street z = m out follow me the centerline the the loop, the axial magnetic ar is
The current used in the calculation over is the full current, so because that a coil the N turns, the current used is Ni where i is the existing supplied come the coil.
The Earth"s magnetic field at the surface is about 0.5 Gauss.
