Can the strength of an electromagnet be changed by changing the voltage of the Power Source?
Yes. That's really the only way you have of changing thestrength of the electromagnet while it's operating.
How do you make an electromagnet field stronger?
You could either put a bar of iron in the center of the electromagnet, increase the voltage that you put in, or make more loops of wire.
What voltage should be applied to make an electromagnet?
The strength of the electromagnet depends on the magnitude of the current in the coil around it.The voltage required is only what produces the desired current in the coil. Since the coil is nothing butwire, the resistance is quite low, and a relatively small voltage produces a relatively large current.
Moving a magnet in and out of a coil of wire produces?
That will induce a voltage across the wire.
How do you decrease the electromagnetic force?
Lower the applied voltage. Lower the amount of windings on the core. Increase the distance from the electromagnet.
Can a electromagnet lift 3kg if so how much current ant voltage should you pass?
It will depend on the voltage of the electromagnet. If it does not have enough voltage, then it cannot life 3kg.
Which is better adding coils or upping the voltage to improve an electromagnet?
Upping the voltage is the easiest method to do but you have to be careful of the insulation rating of the wire in the electromagnet coil. As the voltage goes up so does the current and the heat produced by this action. By over exceeding the voltage rating of the wire this will cause the insulation to break down and short the coil out.

What is the highest and lowest voltage of an electromagnet?
The strength of an electromagnetic is determined completely by the current through its coil, and doesn't depend on the voltage across the coil. The voltage will be (current) x (resistance of the coil).

That will induce a voltage across the wire.
How will you make an electromagnet stronger without changing the electric cell fitted to the circuit?
Adding more turns of wire to the electromagnet will make it stronger without changing the applied voltage.
How many volts are needed to lift an electromagnet need to lift a car?
The amount of voltage needed to lift a car with an electromagnet depends on several factors. The size of the coil, as well as the amperage will need to be factored in to know how much voltage will be used.
Does voltage play a role in an electromagnet?
Voltage is the "pressure" that pushes electrons thru a circuit, higher voltage means more current, or amperes. Amperes and the number of turns of wire in the magnet control the force of the magnet
How do you decrease the electromagnetic force?
Lower the applied voltage. Lower the amount of windings on the core. Increase the distance from the electromagnet.
How do you make a electromagnet stronger?
For a simple copper wire around iron nail electromagnet, increasing the number of rounds the copper wire makes around the nail will increase the electromagnet's strength. Also, increasing the voltage applied(adding a battery) will increase the magnetic field.
