Instructions for building an electromagnet. ... It is fairly easy to build an electromagnet. All you need to do is wrap some insulated copper wire around an iron core. If you attach a battery to the wire, an electric current will begin to flow and the iron core will become magnetized.

Electromagnets are found in motors, tape decks, hard drives, VCRs and tons of other devices. Find out what makes an electromagnet "electro" and learn how to make one at home. ... ­Th­e basic idea behind an electromagnet is extremely simple: By running electric current through a wire, you can create a magnetic field.

Making a Stronger Electromagnet; J0727; Objectives/Goals; Objective: The objective of my experiment was to determine how certain variables affect the strength of the magnetic field of an electromagnet. I tested the variables of electrical power (voltage and amperage), wire gauge, number of wire wrappings, and rod width.
