A simple electromagnet can be created by wrapping a coil of wire around a soft iron core, such as a large nail. The electromagnet is a type of temporary magnet in which its magnetic field is produced by electric current and to …
Whenever electricity flows through a wire, it creates a magnetic field. In a single wire, this field is usually pretty weak. A coil, however concentrates the magnetic field. Each coil of wire contributes a small magnetic field and, together, they add up to make a much more powerful magnet.
Try this simulation to see how moving a magnet creates a current in a circuit. A light bulb lights up to show when current is flowing, and a voltmeter shows the voltage drop across …
Put another way, the commutator keeps the magnetic moment of the coil pointing in a direction that always has a component downward – when it is about to start pointing upward, the current direction flips. This page titled …

The Strength of an Electromagnet | Science Project
Objective In this science project, you will make an electromagnet by wrapping a coil of wire around an iron core. You will then investigate whether the number of coils changes the electromagnet''s strength. Introduction Electromagnets, or magnets that use the magnetic field created by electrical current flowing through a wire, lie at the heart of many electrical …
Discover the fascinating phenomenon of electromagnetism and how it relates to electricity, magnets, and light in this interactive article from Khan Academy.
The magnetic field deep inside the coil is generally aligned with axis of the coil as shown in Figure (PageIndex{3}). This can be explained using the result for the magnetic field due to a straight line current (Section 7.5), in which we found that the magnetic field follows a "right-hand rule."
Electromagnetic or magnetic induction is the production of an electromotive force (emf) across an electrical conductor in a changing magnetic field. Michael Faraday is generally credited with the discovery …
2) Locate a rod or tube that is just a little larger in diameter than the diameter of the battery. We found that a piece of 15mm diameter copper pipe is perfect if using an AA battery. 3) Take your bare copper wire, we found 0.8mm diameter works well, and wind it tightly around the rod, tube or pipe to create a tightly bound coil. ...
