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 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.
Strong temporary magnet formed when a current is passed through a coil of wire?
A magnetic field.
Can you make an electromagnet with aluminum wire?
No. You should use a wire with the best electric conductivity (copper or silver) and wrap it around a (soft) iron core. The wire creates the magnetic field, the iron core concentrates it and turns into a magnet when a voltage is applied to the wire. Iron has rather poor conductivity and malleability so is not suited as the coil of an electromagnet.
What role did sacrifice play in Aryana socaity?
what role did sacrifise play in Aryans society
What is a magnet made by electric current?
An 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.
What is the average voltage of an electromagnet?
a magnet does not have any voltage, only a magnetic field.
How is the role of an electromagnet in a motor different from the role of an electromagnet in an generator?
I thinkit is different because a motor changes eletricalenergryinto motion a generator changesa motion into eletericalenergy.
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 describes the role of an electromagnet in a generator?
Its role is to change mechanical energy into electrical energy.
How does the strength of a wooden core electromagnet compare with that of the iron core electromagnet?
Electromagnets consist of wire coiled around a core. The core can be anything from air to a nail or even a pencil. Since electrons flow freely through a conductive core (like a nail), an electromagnet made with a metal core will have a larger magnetic field (and thus be stronger) than an electromagnet with a wooden core. The strength of an electromagnet is related to the number of times the wire is coiled around the core and the distance the wire covers across the core. The more coils wrapped closer together, the stronger an electromagnet will be. The amount of voltage running through the wire also plays a role in an electromagnet's strength. More voltage means more electrons moving through the wire and thus a stronger magnet.
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 is the role of an electromagnet in the motor of a kitchen blender?
What does reclamation mean
What is the role of an electromagnet when recycling metals?
The role of an electromagnet is to provide us withrecycled materials. The electromagnet is what picks up our heavy metal bits and bobs and moves it or drops it from a certain height so that the metal breaks and can be used again to make another car .
What best describes the role of an electromagnet in a generator?
Its role is to change mechanical energy into electrical energy.
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.
