Yes, but only in a transient manner. Inductors do their "magic" in AC circuits, presenting an inductive reactance that appears as resistance. In a DC circuit, an inductor will simply ramp up current until one of the circuit limits is exceeded, at which point either nothing further will take place, or something will get damaged.
In the worst case, of an ideal inductor with an ideal power source, with ideal conductors, the current will linearly ramp up to infinity.
Don't misunderstand. We do use inductors in DC circuits. The most common use is as a relay or solenoid, or a DC motor, but there is also resistance or time limits involved which places a limit on the steady state current.

When inductor is called short circuit and open circuit?
In DC inductor is short circuited .
If an inductor and a switch are connected in parallel through which the current will flow in an AC circuit?
A:The inductor does not allow ac signal to pass through. It blocks ac and passes dc. If the switch is open, then the ac signal wont pass. If the switch is closed, then the ac signal will pass through the switch.AnswerIt is incorrect to say that an inductor 'does not allow' the passage of an alternating current. An a.c. current will pass through an inductor, although the inductor will limit the value of that current due to the inductor's inductive reactance. Inductive reactance, which is expressed in ohms, is directly-proportional to the inductance of the inductor and to the frequency of the supply. The value of the current is determined by dividing the supply voltage by the inductive reactance of the inductor.If the switch is connected in parallel with the inductor, then closing the switch will apply a direct short circuit across the inductor, and the resulting short-circuit current will cause the circuit's protective device (fuse or circuit breaker) to operate.
What will happen if inductor connected with DC supply?
i think in case of dc supply there will not be any induction
What is the var meter?
A VAR Meter is used to measure Reactive Power in AC Circuits - Pure reactive components dissipate zero power, which makes sense in a DC circuit, as a capacitor passes no DC current and an inductor displaces no voltage. Yet, in an AC circuit, the reactive components "seem" to dissipate power, as current passes through the capacitor and the inductor sees a voltage drop. This counterfeit power is called "reactive power" and is measured not in Watts, but in VARs (Volt-Amps-Reactive). Its mathematical formula symbol is "Q".

Capacitor inductor circuit which smooth out rectified ac voltage are known as?
filter circuits
When inductor is called short circuit and open circuit?
In DC inductor is short circuited .
Will an inductor work on DC?
An inductor cannot work in dc because the frequency is zero there by making the inductive reactance zero as a consequenceAnswerOf course an inductor can work in a d.c. circuit!
Why doesnt a field coil in a DC shunt motor lead to short ciruit when it is a fact that an INDUCTOR is a short circuit to DC?
Yes, an inductor is a short circuit to dc...that's true....IF the inductor is an ideal one, that is, the inductor has no resistance but has inductance only. Anything in real world, as you know, is not ideal. An inductor is usually made of a copper wire. A copper wire has its own resistance. If an inductor coil is thin and long (i.e. many turns), it will provide an appreciable resistance to DC, and will no longer be a short circuit.
Why inductor block ac and pass dc?
When your circuit starts up, your inductor creates an electrical current in the opposite direction. With dc, this effect vanished after the circuit is started. With ac, the current keeps starting and stopping so the inductor keeps creating a current in the opposite direction.
Why we use the inductor?
To answer these questions I will tell you which devices or equipments are inductive.These include:TransformersHair clipers,hair blowers,motorsYou hopefully know what those devices or equipments are used for,hence why we use inductors.
Why you use inductor?
we use the inductor because it helps the circuit to have an appropriate amount of current, so that the circuit in the appliance will say longer.
How can convert pulse setting DC to continus DC?
We can use an inductor in series with the circuit to minimize pulses or ripples in the D.C. The inductor provide zero impedance for a D.C source, but provide high impedance for a pulsated wave, so it will not allow pulses to pass through it. A high inductance in the circuit provides smooth D.C. On the other hand we can have a capacitor in parallel to the output.
Can we use a DC source with an inductor?
Yes, an inductor allows DC to pass through it. An inductor resists a change in current, proportional to inductance and voltage. At equilibirum, an ideal inductor has zero impedance. The differential equation for an inductor is di/dt = v / l
What happens if dc supply is connected to incomer of transformer?
If a DC supply is connected to the incomer of a transformer, you effectively have a short circuit, because the DC impedance of a transformer (actually, any inductor) is quite low. You will blow something.
What is the use of resistance in a LC circuit?
every inductor has some resistance. In circuit diagram, ideal inductor is shown in series with a resistor(value being equal to coil's resistance) to make analysis easy.

Does an inductive load affects the dc power supply?
Inductor acts like a open circuit to DC at t=0 i.e at instant of closing the switch. Because it does not allow sudden change in current. Refer v= L di/dt. As t-> infinity, inductor acts like a short circuit(if pure).
