Yes, insulated wire is commonly used to make electromagnets. The insulation helps to prevent the wire from short-circuiting and allows the current to flow effectively through the wire to create a magnetic field. Insulated wire also helps to protect against electrical shocks and keeps the wire from contacting other conductors.
You can turn a piece of iron into a temporary magnet by stroking it with a permanent magnet in the same direction multiple times. This process aligns the magnetic domains within the iron, creating a temporary magnetic field.
To make an electromagnet with a wire, a nail, and electricity, wrap the wire around the nail to create a coil. Connect the ends of the wire to a power source, such as a battery. When the electricity flows through the wire, it generates a magnetic field, magnetizing the nail.
You can pull the cord from the magnet to make it weaker so it wont pick up as many items you think it will
Get a piece of soft iron (a piece of mild steel will do), and wind some insulated copper wire around it. Check the resistance of the coil of wire to make sure you have a suitable power supply (use V=IR), and apply a current - job done.
To make a simple electric motor for a science fair project, you will need a battery, a magnet, insulated wire, a small piece of cardboard, and a paperclip. Wind the wire around the cardboard to create a coil, attach the ends of the wire to the battery terminals, and place the magnet next to the coil. When the battery is connected, the coil will spin due to the interaction between the electric current and the magnetic field, creating a simple electric motor.
An electro magnet!
Electro-Magnet
an iron nail, a long peice of wire, a large battery or a transformer
Wrap copper wire around a nail, then attach the ends of the wire to a D battery with tape to make an electromagnet.
Any time a magnet passes through a coil of copper wire (the electro magnet) it produces electricity. In all reallity, you don't really have an electro magnet in a generator. Since the Coil or(field) is making the electricity instead of using electricity, the electro magnet isn't really a magnet; but more like an "anti-magnet" :)

no you just need something metal like an iron nail and wrap a coil of un-insulated wire around it and send a current through the wire.
Removing the insulation from copper insulated magnet wire can expose the conductor to the external environment, leading to potential short circuits, electrical shocks, and damage to the wire. It is important to keep the insulation intact to maintain the safety and integrity of the wire when used in electrical applications.
which end of a magnet will pick up an iron nail?
a magnetic field
