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
Is a toothpick a part of an electromagnet?
Not generally, although MacGuyver could make an electromagnet with a toothpick and a spool of wire.
Which is not a way to make an electromagnet stronger?
To chew on it.
Would spinning the loops on an electromagnet make it stronger?
Spinning the loops on an electromagnet will not make it stronger. The strength of an electromagnet depends on factors such as the number of loops in the coil, the current passing through the coils, and the core material used in the electromagnet. Spinning the loops will not change these factors.
What is a magnet made with a battery?
An electromagnet. Anytime electrical current flows through a conductor, a magnetic field is produced.
What must pass through a coil in order to make an electromagnet?
An electrical current will cause an electromagnet to energise.
