To make a small electromagnet all you need is an iron nail and some fine isolated wire. Wind a couple of feet of the wire around the nail then connect one side of the wire to the positive side of the battery and the other to the negative. At the moment they are connected to the battery the nail is a magnet and as soon as the power comes of it will have lost most of its magnetism. Just an ordinary torch battery will do.

What is a magnet made with a battery?
An electromagnet. Anytime electrical current flows through a conductor, a magnetic field is produced.
Why electromagnet is different from a permanent magnet because an electromagnet what?
Mainly in that the electromagnet is NOT permanent. In other words, it can be switched on and off.Another relevant difference is that the electromagnet constantly requires power, at least while it is on.
What kind of investigatory project can a grade 6 pupil do?
Grade 6 can make science investigatory project Like: Horsetail can make us beautiful. Electromagnet. Guava can make into soap. Ashitaba leaves.
What category of science does light fall under?
Physics. Specifically electromagnetism.
How can you make your spherometer more sensitive?
By using an electromagnet with a variable resister to finely-balance your spherometer's intrinsic, counter-clockwise torque--assuming that you are in the northern hemisphere. If you are in the Southern Hemisphere, then you'll simply need to reverse the polarity of your electromagnet.
What is the difference between electromagnetism and electromagnet?
electromagnetism is the force an electromagnet is the object
What kind of energy does an electromagnet use?
electromagnetism
How is electromagnetism created?
An electromagnet is created by running electric current through a coiled conductive wire.
What are the advantages and disadvantages of electromagnetism?
an electromagnet requires electricity and you will have to pay for it. permanent magnets are always on and you can change the strength of it.
How do you use electromagnet in a sentence?
Electromagnetism occurs when an electric current is sent through a coil of copper wire that is wrapped round an iron core.
What is transferred by electromagnet waves?
Electromagnetic radiation is transferred by electromagnetic waves. Electromagnetic radiation is a fundamental phenomenon of electromagnetism.
How do you make a railway signal using electromagnet?
how to make road rail signal using electromagnet
What are the properties of Electromagnetism?
An electromagnet is created when an Fe core is wrapped in a conductor and an electric current goes through the conductor; magnetism and electrical current have a symbiotic relationship -- when a conductor is moved in a magnetic field, electrons start to move and when electrons move through a conductor, a magnetic field is created around the conductor; a simple motor uses an electromagnet to do work.
Is a toothpick a part of an electromagnet?
Not generally, although MacGuyver could make an electromagnet with a toothpick and a spool of wire.
Why are integrated circuits used in electromagnetism?
The question doesn't make sense.
Which is not a way to make an electromagnet stronger?
To chew on it.
What is a magnet made with a battery?
An electromagnet. Anytime electrical current flows through a conductor, a magnetic field is produced.
