It is called an Electromagnet, when disconnected, it loses it's magnetism.
Lemon juice is an acid. The metal in the paper clip reacts with the acid to produce an electric current. It's the same process as the electricity produced in a battery.
A simple block of magnetized iron is called a magnet.
The current produces the magnetic field; such a magnet is called an electromagnet.
A 9 iron is also commonly called a pitching wedge in golf.
It is made of a type of magnetic iron called magnetite.
Wind a piece of wire around the iron core (about 6 or 7 times should do it) and connect both ends to the battery - this makes the iron magnetic - which will lift small metal objects such as paper-clips and drawing pins. The magnetic property is lost when you disconnect the battery.
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.

This would be an Electromagnet...... If the battery is disconnected, then the iron bar will become a permanent magnet.
You need 3 main things: An iron core, a roll of insulated copper wire and your source of electricity Firstly find a suitable iron core a iron nail will do (6in 15cm) next wrap the wire (thicker is better) as neatly and tightly as you can around the iron nail. Once the iron is wrapped up tight make sure you have a piece of copper wire comin off each end one where you began the other where you finished wrapping. Now all you need to do is connect it to your battery which terminal you connect each wire will determine current flow. The power of your electromagnet will depend on the wrapping of copperbut mainly the battery and the current it puts out to great a current will heat the wire quickly but a 9 or 12v battery should be fine.
Any current will produce a magnetic field. If you let a current pass through the wire, you got your magnetic field.Note: If you connect the wire directly to the battery, without any resistance, you'll most likely destroy the battery, due to a short circuit.
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.
yes, just dont connect your iron!
lead acid gives you more usage.nickel iron is less explosive. you decide dude. until next time...........
You will need a soft iron or steel core, insulated copper wire, and a power source such as a battery. By wrapping the wire around the core and connecting it to a power source, you can create an electromagnet.

Usually a li-ion (lithium iron) battery.
