In this day and age with oil prices rising and the recession hitting everyone, more people are looking for more ways to save on cost of the most used items. Electricity is the most common and used item people use in everyday life, but what they do not know is that there is a simpler way to produce electricity with magnets. How do magnets produce electricity? Why not use magnets to produce all electricity? These questions are common in people that research different avenues to provide electricity without having to spend a fortune on other renewable energy sources. Magnets and all their uniqueness is the key to the future discoveries and creation of new machines that produce electricity without using fossil fuels.
Magnets have unique characteristics unlike other metals. The best suited metals for magnets are iron, cobalt, nickel, or mixtures of the metals like steel. Magnets come in all different shapes and sizes, but the typical shapes are the straight or horseshoe magnets. The unique characteristic of magnets is that it has a north and south pole just like Earth. The poles on a magnet can be located on many different positions on the magnet itself as long as one side is north and the other side is south. The magnet’s poles are the reasons why magnets can produce electricity. Magnets are used in all types of electrical applications and without magnets the technology that people take for granted would not be possible. “Magnets are essential for the generation of electric power and are used in motors, generators …” (Magnet).
However, understanding magnets at the atomic level will give the source to why magnets have a south and north pole. The electrons of an atom are similar in all atoms for they spin or rotate as they move around the center of the atom just like the Earth rotates as it moves around the sun (Huntington). Since electrons have an electric charge and they spin, they are called a charge in motion. The electrons, in the metals of magnets, move in one direction. In essence as electrons move through the magnet they create an electric force that surrounds the magnet. The force can be felt with the use of two magnets. Since opposites always attract, forcing two magnets to touch will only work if one magnet’s north pole is facing the other magnet’s south pole and vice versa due to the force created by the electrons. The electric force created by the movement of electrons is called a magnetic field (magnetism).
Due to electrons, magnetic fields around magnets have a lot in common with electricity. In 1820, H.C. Oersted discovered by accident that a needle of a magnetic compass is redirected by a wire carrying an electric current (magnetism). Since a magnetic compass works by its needle lining up with the magnetic forces of the North Pole and South Pole of the Earth, it was evident that electric currents create a magnetic field like a magnet. Therefore, an electric current and magnets both create a magnetic field due to the movement of their...

Electromagnets are magnets that uses an electric current to attract metal. Electromagnets have many parts that make up them and are used in many things. Electromagnetism has a history that dates back over 200 years. The year 1700 was the first demonstration of an electromagnet, yet scientists didn't know much about electromagnetism (Bellis

The only solution for this is to increase the strength of the magnets, as a stronger magnet will produce more energy.While the motor itself has changed since it was first built in 1832, the motor has been used in various appliances. In the past, the motor had been used to power the very first electric motor vehicles. Nowadays, we have

Electrons flow from the battery into a wire, and must travel from the negative to the positive terminal for the chemical reaction to take place. Once you connect a wire, the reaction starts. The first battery was created by Alessandro Volta in 1800. To create his battery, he made a stack by alternating
