first, you have to have a ferromagnetic core, like an iron bolt.
then, you wind a magnetic wire around it. the thicker the winding, the stronger the magnet.
the tips of the wire should be protruding so you can connect it to a source. skin the tips of the wire, too.
connect the wire to a dc source and you got an electromagnet.

What is an electricity magnet?
An electromagnet is a device that produces a magnetic field with the use of DC electricity. A simple electromagnet has a coil of wire wrapped around an iron core. A simple experiment would be to wrap a copper wire around an iron nail then connect both ends of the wire to a small battery. You will notice the nail is magnetized as long as the battery is connected.
What happens when you decrease the current in an electromagnet?
When you decrease the current in an electromagnet, the magnetic field decreases.
How do you make a railway signal using electromagnet?
how to make road rail signal using electromagnet
Does using thicker wire make a electromagnet more powerful?
The wire in a electromagnet is the conductive property transferring power. The thicker the wire the more power transferred to the electromagnet for a exponential amount of power.
How does the number of wraps of wire affect the strength of an electromagnet?
The more turns of wire in an electromagnet the stronger the magnetic field.
Can you give me an example of a simple sentence using the word electromagnet?
There is an electromagnet in that crane
What is the source of electromagnet?
An electromagnet is a type of magnet whose magnetic properties stem from electricity. The earth has a lot of electromagnet waves running through it's surface, which come from the polarization of the planet. A more simple electromagnet can be made by wrapping wire around a metal object and connecting the wire to a battery (just be careful).
What is a magnet made by electric current?
An electromagnet.
What is generator made of?
an electromagnet
What is a generator made of?
an electromagnet
How is a simple electromagnet created?
By passing an electric current through any conductor, a magnetic field will be created. Therefore, a simple electromagnet can be created by connecting a power source to a coil of copper wire.
A wire that carries electricity and is coiled around a nail makes a simple?
electromagnet
How could an electromagnet on a crane at a scrapyard be made to pick up heavier cars?
increase the current on the electromagnet
Can cast iron be made into an electromagnet?
yes
What is the purpose for an electromagnet in a simple doorbell?
to produce magnetic field to move the piston of the doorbell
I have made a simple ir circuit that switches an LED on and off How can you replace the LED in the circuit with a homemade electromagnet so it can pick things up when triggered?
To create an electromagnet, you need to find a nail or similar long piece of ferrous metal. Then, take a wire and tightly wrap a wire around it as many times as you can in continuous coils. All you have to do once you have made the electromagnet is connect the two ends of the wire into your previously created circuit.
Does making the core of an electromagnet larger make it weaker?
No, the electromagnet is not made weaker by making the core larger. It can be made weaker by decreasing its current and/or turns of coil.
