Examples of magnetic circuits include Transformers, inductors, and magnetic cores in motors and generators. These circuits consist of magnetic materials that guide the flow of magnetic flux from one component to another, allowing for efficient transfer of energy and operation of electrical devices.
Resistance to movement of magnetic lines of force is described as reluctance. Reluctance is similar to resistance in an electric circuit and is a measure of the opposition that a magnetic circuit offers to the magnetic flux. It depends on the material and the geometry of the magnetic circuit.
Leakage flux is the flux that does not follow the intended path in a magnetic circuit. It represents the magnetic field that strays outside of the core and does not contribute to the desired magnetic coupling between the components of the circuit. Strategies such as improving the design and materials of the magnetic circuit can help minimize leakage flux.
An electric current flowing through a circuit causes a magnetic field. This is due to the movement of electric charges, usually electrons, in the circuit. The magnetic field produced is perpendicular to the direction of the current flow.
When you close the circuit, a magnetic field is produced which can deflect the compass needle. The direction of the compass needle will align with the magnetic field produced by the current flowing through the circuit.
Magnetomotive force is the magnetic quantity expressed in ampere turns. It represents the total magnetic field strength generated in a magnetic circuit.
There is no element to heat to complete the circuit. Another example would be magnetic induction lighting.

Magnetic circuit follows equation (4) that is Ni = (Ф) ( l / μA) or m.m.f(magneto motive force) = (Flux) (reluctance).Electric circuit follows ohm's law that is E = I.R or e.m.f(electro motive force) = (current) (Resistance)From above point m.m.f in magnetic circuit is like as e.m.f in electrical circuit.Flux in magnetic circuit is similar as current in electrical circuit.Reluctance in magnetic circuit, S = ( l / μA) is similar to resistance R = (ρl/A) in electric circuit.Permeance (= 1/reluctance) in magnetic circuit is equivalent to conductance (=1/resistance) in electric circuit.In magnetic circuit flux establishes but not flow like as current in magnetic circuit.In magnetic circuit energy needed only to establish the flux but no consistent energy need to maintain it whereas in electric circuit continuous energy needed to flow of current.Resistance of an electric circuit is constant (for same temperature) and is independent of current but reluctance of magnetic circuit is not constant because it depends on μ (=B/H) which is not constant and depends on B/H.
The air gap in a magnetic circuit is important because it increases the reluctance of the circuit, which in turn influences the magnetic flux and magnetic field strength. By controlling the size of the air gap, we can control the level of magnetic flux and magnetic force produced in the circuit. This can be useful in applications where precise control over magnetic properties is required.
A circuit is a path for charge particles -- it conducts current. An inductor, a circuit component, generates a magnetic field, when an AC is on. ======================
Leakage flux is the flux that does not follow the intended path in a magnetic circuit. It represents the magnetic field that strays outside of the core and does not contribute to the desired magnetic coupling between the components of the circuit. Strategies such as improving the design and materials of the magnetic circuit can help minimize leakage flux.
Some examples of dynamic units are magnetic disks, magnetic drums, and magnetic tapes
Perpendicular to the circuit.
Saturation in a magnetic circuit refers to the point at which the magnetic material can no longer be magnetized fully. Once saturation occurs, any further increase in magnetic field strength will not result in a significant increase in magnetization. This can limit the amount of magnetic flux flowing through the circuit and reduce the overall efficiency.
The reluctance symbol is a measure of the opposition to magnetic flux in a magnetic circuit. It is represented by the symbol "R" and is the reciprocal of permeance, which is a measure of the ease with which magnetic flux is established in a material or circuit.
