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

1. Move the compass slowly along a semicircular path above the bar magnet until you’ve put it on the opposite side of the bar magnet. Describe what happens to the compass needle.

There are many different theories to magnets ,but one that interested me the most was the legend of an elderly Cretan shepherd named Magnes.He discovered ‘’lodestones’’ which attracts lead.Lodestones contained magnetite, a natural magnetic material( Fe3O4). This rock was named magnetite, after either Magnesia or Magnesia himself.

William Gilbert studied magnetism in the Elizabethan Era. Gilbert was born in England in 1544 (Rich). According to an article written by A.V. Helden, Gilbert attended Cambridge University in 1558. He got his B.A. in 1561, his M.A. in 1564, and his M.D. in 1569 (Helden). Gilbert made discoveries mainly in magnetism. He published a book called De Magnete, which is all about how magnetism affects the world. One of the topics covered in the book was compasses because they were important for the explorers of that time.

The last week of with the lab assignment I see this tool can really save some time in completing job but can easily destroy them if you’re not careful. Also, when it comes to work to precision work like honing and polishing a trigger and sear. Hand files and honing stones should always be used. My first concern was the safety portion of the job. You’re talking about a tool that move at high and low speeds, so I would defiantly wear eye protection. Have a good grip of the tool and to keep your free hand a safe distance away from the rotating bit. I would also be sure do not wear loose clothing or jewelry that can become entangled with the rotary tool. A dust mask is also recommended. At 28,000 rpm, the rotary tool will create a lot of dust.

There are three requirements for the magnetic fields: “A large reservoir of fluid that can conduct electricity

Transportation is a main problem in society. To understand this, you need to know the relationship between magnetism and temperature. It is important to understand this because in Japan, bullet trains operate using extremely cold magnets. People also want to know more about them as they become more popular! Repeated experimentation by experts say that if the magnet is cold, the strength of it will go up. To understand this, you need to know about magnetism, temperature, and magnetism strength.

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.

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

I am extremely sorry for my inappropriate actions that negatively affected your ability to run the classroom effectively. I understand you concerns due to the inability of knowing where I was to assure my safety. I apologize for breaking the rules that are in place to keep every student at Vero Beach High School safe and secure. It was very rude of myself to leave the classroom before asking you to complete work in another classroom. It was inappropriate of me to create a disruption and concern in the classroom. I acknowledge my wrongdoings negatively affected you and the school because my location was unknown. I understand that I fall under the rules that are set for the entire school. My actions were extremely juvenile and disrespectful to

A magnet is anything with a magnetic field. Magnets attract ferrous objects like pieces of steel, iron, nickel and cobalt. They slightly attract liquid oxygen and other materials and they slightly repel water, carbon and boron.

An electro magnet is a type of magnet in which a magnetic field is created by a current, in our case of the

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:

Magnetic repulsion works on the principle of using electro magnets to levitate objects. Unlike normal magnets, electro magnets are created by the movement of current through wires. This means that the strength of the magnet can be changed by increasing or decreasing the current in the wire. As well as this, it is possible to change the poles of the magnet. This is important as it allows the magnet to both push and pull depending on the current. Using the idea that north repels north and south repels south, if the ground were to have the same pole as the electric magnet, then the electric magnet would hover. This idea can better be seen in figure 1.
