To build an electromagnet, you will need a strong ferromagnetic core, such as iron, to enhance the magnetic field. You'll also need insulated copper wire to create the coil around the core, and a power source, such as a battery, to supply electricity. Additional tools like wire cutters, a switch, and electrical tape may also be useful for assembly and safety.
Ivan will need a power source (such as a battery), a coil of wire, and an iron core to build an electromagnet.
No, a pencil is not a good core to build an electromagnet. Electromagnets typically require ferromagnetic materials like iron, nickel, or cobalt to enhance their magnetic properties. Pencils are made of graphite, which is not ferromagnetic.

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.
A nail, copper wire, paper clips, staples and power supply.
Iron, Nickel, Cobalt
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.
You need a design for a helicopter. That design will tell you what materials you need...because every heli has different materials in it. The things you need to build a Robinson R-22 are different from the things you need to build a Sikorsky CH-53E.
An electromagnet can repel materials that are either ferromagnetic (such as iron or nickel) or paramagnetic (such as aluminum or copper) when it is energized. Non-magnetic materials like wood, plastic, or glass will not be affected by the repelling force of an electromagnet.

You need 10 soft clay.
To build a house, you will need materials such as wood, concrete, steel, and bricks. You will also need resources like tools, equipment, labor, and a blueprint or design plan.
