Because bare wire would short out as the wires are touching each other.
Copper wire used in electromagnets is insulated to prevent short circuits and to protect the wire from damage due to abrasion or exposure to moisture. Insulation also helps to maintain the efficiency and longevity of the electromagnet by ensuring the electrical current flows properly through the wire.
To make an electromagnet, you need a magnetic core (such as iron), an insulated wire to create a coil around the core, and a source of electric current to flow through the wire and create a magnetic field.
To make an electromagnet, you will need a core material (such as iron or steel), insulated copper wire, a power source (such as a battery or power supply), and a way to connect the wire to the power source (such as a switch). Simply wrap the wire around the core material, connect the ends of the wire to the power source, and when current flows through the wire, it will create a magnetic field in the core, turning it into an electromagnet.
Stacie should connect the ends of the bar to a power source, such as a battery, using insulated wire. The flow of current through the wire will create a magnetic field around the bar, turning it into an electromagnet.
You will need a power source such as a battery, insulated copper wire, an iron core (such as a nail), and a switch to build an electromagnet. Wrapping the wire around the iron core and connecting it to the power source will create a magnetic field when the current flows through the wire.

So the wire doesn't short itself out. The electricity needs to go through all the windings individually.

You will need a power source such as a battery, insulated copper wire, an iron core (such as a nail), and a switch to build an electromagnet. Wrapping the wire around the iron core and connecting it to the power source will create a magnetic field when the current flows through the wire.
To conduct an experiment on an electromagnet, you can start by wrapping an insulated copper wire around an iron nail. Connect the wire to a power source such as a battery. When the current flows through the wire, it creates a magnetic field, turning the nail into a temporary magnet. You can test the strength of the electromagnet by observing how many paper clips it can pick up.
To make an electromagnet toy, you will need a battery, insulated copper wire, a small metal rod or nail, and a switch. Wind the copper wire around the metal rod tightly, leaving ends free. Connect the wire ends to the battery terminals with the switch in between and when you turn on the switch, the current will flow through the wire creating a magnetic field, turning it into an electromagnet.
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.
The first electromagnet was built by William Sturgeon in 1825. Sturgeon discovered that wrapping an insulated wire around a horseshoe-shaped iron core and passing an electric current through the wire created a magnetic field. This invention laid the foundation for the development of various electromagnetic devices and technologies.
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.
