When current flows through an inductor, a magnetic field is created.
That's the simple explanation. More formally, an inductor is a magnetic device that reactively resists a change in current by presenting a voltage backwards towards the source. The equation for an inductor is ...
di/dt = v/L
... which means the the rate of change in current in amperes per second is proportional to voltage in volts and inversely proportional to inductance in henrys. Theoretically, this means that, if you place a constant voltage across an inductor, current will linearly increase without bounds to infinity. Practically, this will be limited by resistance and current capacity.

Why is the parallel resonant circuit called an rejector circuit?
THE PARALLEL rlc CIRCUIT IS CALLED A REJECTOR CIRCUIT BECAUSE IT REJECTS DOWN THE CURRENT. THE REASON IS AT RESONANCE THE IMPEDENCE OF THE CAPACITOR BECOMES EQUAL TO THAT OF THE INDUCTOR SO NO CURRENT FLOWS. AT LOW FREQUENCY THE CAPACITIVE REACTANCE IS LOW SO ALL THE CURRENT FLOWS THROUGH THE INDUCTOR AND WHEN THE FREQUENCY IS HIGH ALL THE CURRENT WILL FLOW THROUGH THE CAPACITOR BECAUSE AT THAT POINT THE REACTANCE OF THE CAPACITOR IS LOW. SO WE OBTAIN A V-SHAPED GRAPH WITH THE PEAK OF V INDICATING THE REJECTION OF CURRENT.
What happens to the current at a junction in a parallel circuit?
In a parallel circuit the current divides when it comes to a junction. Part of the current flows through one branch and the other part flows through the other.When the two branches have the same resistance, the same current flows through each branch.When the two branches have different resistances, a bigger current flows through the branch with the smaller resistance - it's just easier this way!Hope i helped ;)
What happens when a direct current is passed through a helical spring?
in an adjacent coils ,the current flows in same direction so there is force of attraction shortening the coils.
The total current that flows through a circuit is the same as the current that flows through each individual resistor connected in series?
True
Why is there no inductive reactance in DC circuits?
Inductive reactance is a resistance by inductors to the change of current flow, and is dependent on the frequency at which the current oscillates. DC current flows in only one direction so an inductor's impedance remains the same.
How does current flows when inductor n capacitor r in series?
The stronger the magnetic field on your inductor the greater amount of current you will have flowing through your series circuit.
How does an inductor work?
An inductor works by storing energy in a magnetic field when an electric current flows through it. This magnetic field resists changes in the current, which can be used to control and regulate the flow of electricity in a circuit.
Equaction of energy related to inductor?
Energy stored in the inductance 'L' through which the current 'I' flows is [ 1/2 L I2 ].
How does an inductor work to store and release energy in an electrical circuit?
An inductor works by storing energy in the form of a magnetic field when current flows through it. When the current changes, the magnetic field also changes, inducing a voltage in the inductor. This stored energy can then be released back into the circuit when needed.

How does an inductor work and what are its key functions in an electrical circuit?
An inductor works by storing energy in a magnetic field when an electric current flows through it. Its key functions in an electrical circuit include resisting changes in current flow, filtering out high-frequency signals, and storing energy that can be released when needed.

How inductor produces magnetic field?
An inductor produces a magnetic field when current flows through it, according to Faraday's law of electromagnetic induction. The magnetic field forms around the inductor's coil due to the flow of electricity, creating a magnetic flux that can store energy in the form of magnetic field lines. This magnetic field is what allows inductors to store energy and resist changes in current flow.
What happens to the charge of a wire when a current flows through it?
When a current flows through a wire, the charge within the wire does not change. The charge carriers (usually electrons) move along the wire, creating an electric current, but the total charge remains constant.
What happens to the coil when a current flows through?
When a current flows through a coil, it generates a magnetic field around the coil according to Ampere's law. This magnetic field can attract or repel other nearby magnetic materials and can induce a voltage or current in nearby conductors through electromagnetic induction.
