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.

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.
Can a magnet lift you of the ground?
An electromagnet can, but you have to grasp metal for it to pull on.
How is electromagnet the same as permanent?
An electromagnet is only magnetic while current is flowing through the coils. A permanent magnet is always magnetic, and does not need electricity. An example of an electromagnet at work is in a metal scrape yard, where a large electromagnet is used by a crane operator to lift ferrous metals into a crusher (scrapped cars, for instance). The metal drops into the crusher when the electricity is switched off by the crane operator. Therefore, they are only really similar when both are magnetised.
Would a powerfull electromagnet lift a needle out of a haystack?
Only if the needle was made of iron or copper
An electromagnet would most likely be used as a what?
A device on the end of a crane to lift cars and junk
What is a example of converting electrical energy into magnetic energy?
An electromagnet, a coil of wire round a magnetic core. An electric current in the wire produces a magnetic field round the core, which contains energy which could be used to lift a load.
What is an eletro magnetic?
Electro magnets are only magnetic when an electric current is flowing, unlike a standard magnet which is always magnetic. When the electric current is switched off, the magnetism decays away (collapses). They normally take the form of a fixed core made of soft iron surrounded by a coil of copper wire which acts as the conductor for the electric current. There is a special form of electro magnet which has a movable core instead of it being fixed and this type of electro magnet is called a solenoid. You can see large electro magnets at work at a scrap metal yard, where they are employed on a crane jib to lift and transport scrap iron and steel.
Why is a crane in a steelworks fitted with a large electromagnet?
Because they can then lift the steel easily without having to put chains and lifting gear onto it.

10 ways an electromagnet can be used?
1. to make electricity 2. to lift up cars 3. motors 4. speakers 5. MRIs ...
What is a lifting magnet?
A lifting magnet is an electromagnet that is meant to hold or move material that comes in contact with the magnet. This is the opposite of a traction magnet.
Can an electromagnet lift metal at a water depth of 300 feet?
The magnet on the surface and the metal 300 ft down - no. Lowering the magnet to the metal, then lifting - yes.
