Parallel Magnetic Circuit A magnetic circuit that has more than one path for the magnetic flux is called a parallel magnetic circuit. It is similar to a parallel electric circuit that has more than one for electric current to flow. Consider a parallel magnetic circuit shown in Figure. A current-carrying coil is wound on the central limb.

The unit of magnetic flux density is the tesla (T) 1 T = 1Wb/m 2. Magneto Motive Force (m.m.f.) It is the cause of the presence of a magnetic flux in a magnetic circuit. Reluctance S (or R M) It is the magnetic resistance of a magnetic circuit to the presence of magnetic flux(Φ). The unit of reluctance is A/Wb or H-1.

The Roller magnetic separator is the ideal solution for such application. The magnetic roller develops 10000 Gauss value on its magnetic poles which enable it to trap & separate even very fine & feeble magnetic impurities. The self cleaning feature makes it preferable to use in continuous production processing lines.
In a ring-shaped electromagnet with a small air gap, the magnetic field or flux is almost entirely confined to the metal core and the air gap, which together form the magnetic circuit. In an electric motor, the magnetic field is largely confined to the magnetic pole pieces, the rotor, the air gaps between the rotor and the pole pieces, and the metal frame.
Magnetic Circuit Analysis 4 fk k = ∑ = 1 3 0 or in general, fk k n = ∑ = 1 0 Having derived the Ohm's law, KVL and KCL in magnetic circuits, we can solve very complex magnetic circuits by applying these basic laws. All electrical dc circuit analysis techniques, such as mesh analysis and nodal analysis, can also be applied in magnetic ...
