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.

Which part of an electric motor connects the power supply to the split-ring and coil?
The part of an electric motor that connects the power supply to the split-ring and coil is called the commutator. It works in conjunction with the brushes, which are conductive contacts that transfer electrical current from the power supply to the rotating coil through the commutator. This setup allows for the continuous rotation of the coil by reversing the current direction at the appropriate moments.
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.
What is meant by operating coil cut-off in trip relay?
Operating coil cut-off in a trip relay refers to the mechanism that interrupts the power supply to the relay's operating coil once the relay has actuated. This cut-off prevents the coil from overheating and ensures that the relay remains in its tripped state until it is manually reset or the fault condition is cleared. By removing power from the coil, the relay can maintain its position without continuous energy consumption, improving reliability and efficiency.
Is it possible to have pure inductive coil?
no
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 do you do when no current is coming to the coil?
Turn the power supply on. Then check all connections.
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)!
How do you find polarity in a coil?
To determine the polarity of a coil, you can use a simple method involving a DC power supply and a compass. Connect the coil to the power supply and observe the direction of current flow; the end where current exits is the positive terminal. You can also use a compass: bring it near one end of the coil while the current is flowing; the end that attracts the compass needle is the north pole, indicating positive polarity.
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
