- 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 = (Ïl/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.

How are electrical circuits different from magnetic circuits?
What are the differences between electrical and magnetic circuit.
Is the magnetic field that is near an electrical circuit parallel or perpendicular to the circuit?
Perpendicular to the circuit.
How does a magnetic transformer work to convert electrical energy from one circuit to another?
A magnetic transformer works by transferring electrical energy from one circuit to another through electromagnetic induction. When an alternating current flows through the primary coil of the transformer, it creates a changing magnetic field. This changing magnetic field induces a voltage in the secondary coil, which then transfers the electrical energy to the secondary circuit. This process allows for the conversion of electrical energy from one circuit to another with minimal loss.
What is the function of a motor in an electrical circuit?
A motor in an electrical circuit converts electrical energy into mechanical energy, causing movement or rotation. It typically consists of coils and magnets that interact to create a magnetic field that generates the motion of the motor.
What are the interactions between magnetic objects and electrical circuits?
When a magnetic object is moved near an electrical circuit, a magnetic field can induce an electric current in the circuit, a phenomenon known as electromagnetic induction. This current can be used to power devices or transmit information. In some cases, electrical current passing through a wire can create a magnetic field, influencing nearby magnetic objects.
What is an electrical circuit that produces a magnetic field?
All electrical circuits produce a magnetic field around the wires when a current is travelling. If we want to generate a large field, we can coil the wire. Such a coil is called a solenoid.
What is a circuit which produces a magnetic field by an electrical current called?
That would be an electromagnet. It consists of a coil of wire through which an electric current passes to generate a magnetic field.
What is the function of fuse in automotive application?
Same as any fuse in an electrical system- to protect components in the electrical system from damage in an overload or short circuit.
What is the function of an electrical coil in a basic circuit?
There are a couple of examples that come to mind where there is a coil in a circuit. One is, the coil is used as a choke to block harmonics from going down the electrical line. Another example of a coil in the line is the coil in a magnetic contactor. When this coil is energized the contacts of the magnetic contactor close.
What are the different types of circuit breakers available in the market?
The different types of circuit breakers available in the market include thermal-magnetic, magnetic, and residual current devices (RCDs). These circuit breakers are designed to protect electrical circuits from overloads, short circuits, and ground faults.
What is the use of conductance?
When referring to electrical conductance, it is used in the application of electricity to equipment. Electrical conductance measures the equipment's ability to conduct electrical charge. A practical application would be to decrease the resistance in an electrical circuit so that the conductance is higher and electricity flows more smoothly.
What is difference between magnetic circuit and electric circuit?
