Simple magnetic circuit

Calculates ideal electromagnet force in a uniform gap from supplied B or from N, I and g.

Calculates H, B and turn density for a long ideal solenoid.

Calculates magnetic flux density at the center of an N-turn circular loop.

Calculates magnetic flux density around a long straight wire from current, distance and μr.

Calculates linear magnetic field energy density from B and constant relative permeability μr.

Converts magnetic field strength H units; it does not mix them with tesla or weber.
