Long straight wire magnetic field

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

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

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

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

Calculates reluctance, MMF, flux and B/H for one core segment with an optional air gap.

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