# Magnet In A Magnetic Circuit

Magnetic flux in the---magnetic space closed paths. Permanent magnetic circuit is based on permanent magnets as a magnetic field source, permanent-magnet excitation of magnetic circuit of magnetic circuit

Closed magnetic circuit the most simple of said ''H along the magnetic field strength, is a small length of magnetic circuit, c is current, f is current flowing through the linking the conductor coil turns into w, by the permanent magnets, iron core and air gap slightly consisting of fishing in a closed magnetic circuit type set up, but can also be on. If increasing magnet the magnetic potential is sufficient to saturation and magnetization of the magnet, magnets magnetic State in m point of saturation magnetization curves in the plane. Become a permanent magnetic circuit are: magnetized the prerequisites first, then remove the magnetic potential of the current garrison of permanent magnetic circuit
