magnetic circuit with air gap
... Fringing Effect: Bulging of the flux lines in the air gap. Effect: The effective cross section area of air gap increase so the reluctance of the air gap decrease. The flux density Bg < Bc, Bc is the flux density in the core. If the air gaps is small, the fringing effect can be neglected. So ...

... convention, we say that the magnetic field lines leave the North end of a magnet and enter the South end of a magnet. If you take a bar magnet and break it into two pieces, each piece will again have a North pole and a South pole. If you take one of those pieces and break it into two, each of the sm ...

When an emf is generated by a change in magnetic flux according to Faraday's Law, the polarity of the induced emf is such that it produces a current whose magnetic field opposes the change which produces it. The induced magnetic field inside any loop of wire always acts to keep the magnetic flux in ...
