Faradays Law

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.

Lenz’s Law: “An induced EMF always gives rise to a current that creates a magnetic field that opposes the original change in flux ”1

“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”

5. Find the maximum separation distance from the primary coil along both the vertical and horizontal axes for each of the various secondary coils. Record results.

Otherwise their static. No one believed Maxwell, and Hertz set out to prove Maxwell right. Hertz used two rods to serve as a receivers. When the applied a spark to one of the rods, he could get it to jump to the other rod. Hertz discovered how to make the electric and magnetic fields separate themselves and travel freely.

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

Drag a magnet the long length of, lift and return the magnet to the beginning end repeat the motion Repeat the motion till it becomes a compass. Why was the paper clip not a compass at first? Why did the clip turn into a compass? 2. Circle Magnet.

A train is travelling with a constant velocity of 80 kmh-1 in a area where the vertical component of the Earth’s magnetic field is 3.6 × 10-5 T. a. b. What is the size of the EMF induced across each 1.0 m long axle? [ 8.0 × 10-4 V] If the train is travelling in a south westerly direction, describe the force acting on the electrons on each axle.

The electrical inventions by Nikola Tesla has influenced modern physicists and technology substantially. Nikola Tesla’s

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

Michael Faraday, son of James Faraday and Margarat Hastwell, was born on September 22, 1791 in Newington Butts, England. Michael was born into a poor family. Michaels father, James, was a member of the Glassite, which was a small christian church founded in 1730 in Scotland, for which he was called a Sandemanian. James was also a blacksmith who had left his smithy in Outhgrill in 1791. This move was done in order for James to pursue work in London. However, the ill health of James made him only capable of providing the bare minimum of basic needs for the family. After his increase in ill health, James died in 1809, leaving Michaels mother, Margarat, to be the mainstay of the family. Margarat did what she could with what she had and remained

A slinky was stretched on the lab bench and taped down with the turns of each slinky at roughly 1 cm apart. Positive and negative alligator clips were then attached to each end of the slinky to allow for current flow through the slinky. Next, a Vernier magnetic field probe was placed in the center of the slinky, zeroed, and set to “high sensitivity” for accuracy. The power supply was then turned on and adjusted until the current reached about 0.5A.

“it's not a dream, its a simple feat of scientific electrical engineering, only expensive, blind, faint-hearted, doubting world”. The Tesla coil was invented by a Serbian man named Nikola Tesla. 1896, that was the year that tesla coils were created. Tesla created this because he wanted a wireless world.

A magnet is an object with a magnetic field. A magnet appeals to any object containing iron. These objects are considered ferrous objects and may include pieces of iron, cobalt, nickel, and steel. The end of a magnet will always point in either the North or South direction. The end that points north is called the North Pole and the end that points south is called the South Pole. It

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:
