Secret of Magnetism Essay

What is magnetism? When two pieces of iron are attracted to each other by physical means or electrical means.

The current has a positive charge in one side of the coil and it transforms to negative when it gets to the other side of the coil. This charge controls the magnetic field, making the like charges repeal and the opposite charges attract.

Magnets have a magnetic field surrounding them and these fields is the magnetism force that the magnet poses of an object. On a large scale, the Earth is a magnet which also has a magnetic field.

Definition First of all, an electromagnet has to be defined. An electromagnet can also be called a Solenoid, Which consists of a core of iron and then wire is wrapped round it.

“To investigate the electrical realm of high-frequency and high-voltage, Tesla invented an apparatus that pushed the limits of electrical understanding. None of the circuit's typical components were unknown at the time, but its design and operation together achieved unique results—not the least because of Tesla's masterful refinements in construction of key elements, most particularly of a special transformer, or coil, which is at the heart of the circuit's performance” (PBS). This new invention would be called the Tesla Coil. This invention of the coil would help Tesla and the world with new inventions. “Tesla made an antenna of the high-voltage end of his secondary, it became a powerful radio transmitter. In fact, in the early decades of radio, most practicable radios utilized Tesla coils in their transmission antennas. Tesla himself used larger or smaller versions of his invention to investigate fluorescence, x-rays, radio, wireless power, biological effects, and even the electromagnetic nature of the earth and its atmosphere”

The Railroad and the Pony Express has been the only way to communicate remotely and send correspondence. Joseph Henry and Samuel F.B. Morse would sculpture the future of communication with the invention of the electromagnet and telegraph. Joseph was a graduate of Princeton (Then called the College of New Jersey) as a physicist. The fascination with electricity and magnetism in which he had read reports on from Europe fascinated his desire to research and develop an electromagnet. This shaped our future of electricity as we see it today. With the ability to distinguish between high amperage circuits and high voltage circuits, this laid the baseline for what we know today as “Inductance”. Electrical conductor produces energy by the changing of current or the changing of voltage to produce a strong magnetic force while only using a small battery. By Joseph Henry’s introduction to inductance also paved a path for the invention of electric motors. These advances in technology developed a method for illuminating homes and streets. The use of electricity was spreading almost as fast as the railroad. This improved the lifestyle and functionality of America. (Tindall, Shi

The electric motors work by electricity and magnets working together. Once the electricity gets going, the magnets take over. The magnets keep the motor going because the magnets used in motors have both positive and negative magnets on both sides. Surrounding the magnetic ends, are one positive and one negative magnet. This means that at any

Magnetism occurs when a magnetic field forms. There are two sides of a magnetic field; south pole and north pole. If the two poles are opposite, they will attract and vise versa. A magnet can magnetize an iron object. Electromagnetic waves work

A magnet is an object that has a magnetic field. It can attract heavy objects such as iron and steel. A magnet can be in many shapes and sizes. The word magnet came from the elderly Cretan shepherd, Magnes. He supposedly found a rock that had a strong magnetic force. In the rock was large amounts of lodestone. The most common magnet used today is the bar magnet. They can also be used in compasses.

Did you know, that energy is absolutely everywhere? Energy flows from the your car battery to the walls of your home. In "Energy Story", the author explains how electricity works through atoms and particles. "Conducting Solutions" explains how different liquids work with electricity. Finally, during the TED video "Hands-On Science with Squishy Circuits", AnnMarie talks about how you can make a simple electric circuit using home play-doh and kitchen materials. Each of these sources have a different purpose, but all three describe and talk about electricity.

How strong is the magnetic field went the length of the coil on the electromagnet is shorter or longer?

Have you ever came home and wondered how do your light turns on and of or why do magnets repel the same poles? A physicist was the reason we have knowledge about electromagnetism today. The factor of this electromagnetic field was when he noticed that electrical fields and magnetic fields can couple together to form electromagnetic waves. Energy consumption has increased over the years because of electricity. In “A Dynamical Theory of the Electromagnetic Field” (1865) James Clerk Maxwell produced the first produce the first complete set of equations governing electricity and magnetism, expressed in terms of fields. The theory of electromagnetism from James Clerk Maxwell which led to the invention of the Electric Grid.

Electromagnets can turn electrical energy into motion. Likewise the converse is true: they can turn motion into electrical energy.

Originally electricity and magnetism were thought of as two separate forces. This view changed, however, with the publication of James Clerk Maxwell's 1873Treatise on Electricity and Magnetism in which the interactions of positive and negative charges were shown to be regulated by one force. There are four main effects resulting from these interactions, all of which have been clearly demonstrated by experiments:
