Yes, it possible to heat a coil using dc power supply.
An inductor resists a change in current, proportional to voltage and inversely proportional to inductance.
The equation of an inductor is di/dt = v/L
An ideal inductor, if connected to an ideal DC supply, with ideal conductors, would ramp up current in a linear fashion without limit, eventually reaching infinity amperes after infinite time. Since no inductor is ideal, nor is any DC supply, nor is any conductor, the current would reach a maximum based on the capacity of the DC supply and the DC resistance of the inductor and conductors.
Since the DC resistance of the inductor is also not zero, this means, by Ohm's law, that the inductor must dissipate some power. That will cause the inductor to heat up.

What do you do when no current is coming to the coil?
Turn the power supply on. Then check all connections.
What could cause voltage in a coil that has no current running through it?
A: A coil does store energy and this energy will be released after the current is removed is evident by a reversal of voltage across it before it collapse finally with less and less voltage <<>> Using a volt meter to ground, you would see the supply potential coil voltage on the coil end, if the return wire from the coil was open.
Is it possible to have pure inductive coil?
no
Advantage of a choke coil over a resistor in a power supply filter?
A choke is an inductor. For typical power frequency, an inductor will slightly change the power factor, but will not actively use much energy. An abnormal voltage spike on a power supply is equivalent to voltage at a much higher frequency. Inductors appear to be a much greater impedance to high frequencies. This allows the choke to pass "normal" power, while at the same time it blocks "abnormal" power.A resistor acts independent of frequency. It will limit the effects of the high frequency voltage spikes by dissipating their energy, but it will do the same for the normal power system frequency. In effect, it is always using power, when the choke only uses what you don't want to get to the power supply.
What happens when a permanent magnet moving coil instrument be connected in an ac current?
The torque on the moving coil will reverse at twice the frequency of the supply, causing the pointer to vibrate. High-quality a.c. measuring instruments that incorporate a moving coil are, of course, common but incorporate a rectification circuit to supply the coil.
How can you measure the ampere or watt for power supply?
You can measure the current and power of a 'power supply', using an ammeter and a wattmeter. With the power supply connected to its load, the ammeter must be connected in series with the power supply's input. The wattmeter's current coil must also be connected in series with the power supply's input, and its voltage coil must be connected in parallel with the supply, taking the instrument's polarity markings into account.
What is the number of turns in primary and secondary coil for 12 volt battery charger with 220 volt power supply?

Difference between shunt coil and tripping coil?
a shunt coil needs external supply & tripping coil gets supply from itself.
What are 3 components of an electromagnet?
Coil of wire: A current-carrying coil of wire generates a magnetic field when electricity flows through it. Core material: A core material, such as iron, helps concentrate and strengthen the magnetic field produced by the coil. Power source: An external power source, like a battery or power supply, is needed to supply the current that creates the magnetic field in the electromagnet.
Can you connect pressure coil instead of current coil in watt meter to measure power?
You have to connect both coils to measure power: the current coil in series with the load, and the voltage ('pressure') coil in parallel with the supply. And you have to observe the wattmeter's polarity markings if you don't want it to read downscale (backwards)!
Cylinder 5 misfire could it be the coil pack?
it's possible, also check compression, fuel supply, and vacuum leaks.
What does the auto shut down relay do?
The computer uses it to control the power supply to the fuel pump, injectors, and ignition coil.
Why are you Not getting fire to plugs on 2000 kia?
You will not get fire to the plugs on a 2000 Kia if the ignition coil is defective or it is not receiving power. This can be checked by using a multimeter to verify power levels at the coil.
Can the alternator be mess up an still start car?
Yes as long as the battery has suffient power to crank engine and supply necessary power to allow coil to fire
What does a coil pack do?
The purpose of a coil pack is to supply the spark to the spark plugs.
