Ivan will need a power source (such as a battery), a coil of wire, and an iron core to build 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.
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.
An electromagnet cannot pick up materials that are not attracted to magnetic fields, such as plastic, wood, or glass. It also cannot pick up materials that are too heavy for the strength of the magnet. Additionally, the object may need to be within the magnetic field's range for successful pickup.
An electromagnet needs a wire because electricity flowing through the wire creates a magnetic field around it. This magnetic field interacts with nearby materials to exhibit magnetic properties, essentially turning the wire into a magnet.

To build a triglyceride, you need three fatty acid molecules and one glycerol molecule. These materials combine through a process called esterification to form a triglyceride molecule.
what materials are needed to build a lighthouse
A nail, copper wire, paper clips, staples and power supply.

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.
mostley aluminum
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.
get steel or brick
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.
You need an architectural plan, a building permit, and building materials.
