What flows through a circuit and causes a magnetic field?
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.
What conditions are necessary for magnetic field to produce a force on a wire?
A current has to flow in the circuit to induce a force on the circuit
What flux that does not follow the intended path in a magnetic circuit?
leakage flux
When does electric current behave like a magnet?
An electric current is always surrounded by a magnetic field. This is more noticeable (for example, it can be detected with a compass) in the case of DC, and if the two wires of a circuit are separate.
Example of your life of magnetic force?
gravity is one example
Why does a energy efficient bulb not complete a circuit?
There is no element to heat to complete the circuit. Another example would be magnetic induction lighting.
What is difference between magnetic circuit and electric circuit?
magnetic circit has a magnet and electri circuit has electricity
Application of electrical circuit analogies in magnetic circuit?
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.
Is a circuit a path made for magnetic field?
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. ======================
Is the magnetic field that is near an electrical circuit parallel or perpendicular to the circuit?
Perpendicular to the circuit.
Example of a dynamic memory unit?
Some examples of dynamic units are magnetic disks, magnetic drums, and magnetic tapes
How are electrical circuits different from magnetic circuits?
What are the differences between electrical and magnetic circuit.
What flows through a circuit and causes a magnetic field?
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.
What is inverse of inductance?
reluctance, it is the resistance of a magnetic circuit to the establishment of a magnetic flux by a magnetomotive force.
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 is meant by a magnetic circuit?
Lines of force go from a North pole of a magnet to the South pole external to a magnet, and through the magnet itself. This path is the magnetic circuit. It may be diverted and distorted by magnetic materials nearby.
Is it need iron core in dc generator?
If, by 'core', you mean its magnetic circuit, the answer is yes you do! Without a magnetic circuit, you will not be able to concentrate the magnetic flux within the air gaps enough to produce sufficient torque on the rotor windings.
