What causes electrons to move through a wire as a current?
A voltage, which is related to a change in an electric field.
What is the ohms law formula for a magnetic circuit?
E = IxR where E is Electromotive force measure in VoltsI = current flow measured in AmperesR = total resistance in the circuit.Volts and Amperes are named for people, so are capitalized.AnswerWhat is generally (but incorrectly) called the "Ohm's Law" equation for a magnetic circuit is as follows:magnetomotive force = flux x reluctanceMagnetomotive force (equivalent to emf in an electric circuit) is measured in amperes (but often spoken as 'ampere turns'), flux (equivalent to current in an electric circuit) is measured in webers (pronounced 'vay-bers'), and reluctance (equivalent to resistance in an electric circuit) is measured in amperes per weber (but often spoken as 'ampere turns per weber').
What is the part of an electric circuit generating force?
switch, motor or rotor.
Electromotive force is usually provided by a what or what in an electric circuit?
it is usually provided by a battery or generator.
What is ampere turn formula?
Magnetomotive force establishes magnetic flux in a magnetic circuit, which is opposed by the reluctance of that circuit. It's easy to relate these magnetic quantities to the equivalent quantities in an electric circuit:magnetomotive force is equivalent to electromotive forceflux is equivalent to currentreluctance is equivalent to resistanceA magnetomotive force (mmf) is created whenever an electric current passes through a coil. It's magnitude is determined by the product of the current (I) flowing through the coil and the number of turns (N): mmf = I NThe unit of measurement of magnetomotive force is the ampere. Although, to prevent it from being confused with the unit of measurement for current, it is usually spoken as "ampere turn".
What is the electric force that makes current flow in a circuit is related to is?
The electric force that makes current flow in a circuit is related to the resistance.
In an electric circuit what provides the push?
You could consider the Voltage as the pushing force in a circuit. It drives the current.
What is the term used to measure the force that is applied to an electric circuit to generate the flow of current?
muragapha
4 most important factors in an electric circuit?
electromotive force, current, resistance, and power
If current increases and resistance increases what would cause this?
The only way current can increase while resistance in a circuit increases is if voltage, which is the force that causes electric current, increases.
What kind of force keeps current flowing in a circuit?
EMF (voltage) is the force that keeps current flowing in a circuit.
How does a circuit turn a switch on and off?
A switch makes a physical break in the electric circuit. With the circuit broken the electricity can not flow. When the switch is turned the other way the circuit is completed and the current/electricity can flow.
What is the magnetising force?
its a force that moves by electric current
What causes electrons to move through a wire as a current?
A voltage, which is related to a change in an electric field.
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

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.
