Magnet rough draft essay
Magnets can be used for lots of things whether it is to pick up metal or to produce music. It might sound weird that a magnet can be used to make music but their are tiny magnets in speakers.
Magnets are iron or alloys that have specific atomic structure. This causes the the alloy for example to have the ability to attract other metals. Not every metal can become a magnet, one metal that can be a magnet is iron. There are also electromagnets, these magnets create a field when they are getting an electrical current.
Ancient people learned about magnetism from lodestones, which are naturally magnetized pieces of iron ore.By the 12th to 13th centuries AD, magnetic compasses were used in navigation in China, Europe, the

“You want to attend Manual for high school, only nerds go there.”, many people say. A lot of people don’t understand DuPont Manual high school or the environment. DuPont Manual high school is a place where you can be yourself, while focusing on a certain area of expertise. This school gives someone who wants to be successful, many opportunities in many different areas However, many people have a certain perception of Manual. They feel only “nerds” go there. When actually people who want to experience what success, opportunity, tradition, and a diversity feels like attend DuPont Manual high school. I specifically want to attend the J&C magnet because of my love of writing, reporting, and debating! I’ve always loved to report what is happening in my community and school. I also love debating on certain topics to view different outlooks and opinions.
The magnetic compass was invented no later than the Han period. It uses the earth’s magnetic field to show direction. The compass allowed sailors, navigators of trading ships and warships to travel vast distances. It gave a more accurate direction and has been a key factor in the most important sailing voyages.
The nineteenth century was a very prolific era of discovery in electrical knowledge and technologies that laid the foundation for modern electrical communication. During this period of time the foundations of modern electrically based technologies were discovered. The nineteenth century began with a debate between Luigi Galvani, and Alessandro Volta regarding the source of electricity in Galvani’s famous frog experiment. These debates lead to the invention of the battery by Volta, and the invention of Volta’s. Volta’s discoveries would lead the way for Ohm’s law several years later. However, before that discovery was made Hans Christian Ørstead discovered electromagnetism, which was then used by André Marie Amperè to show that magnetism
Several Chinese inventions improved travel and exploration in Imperial China and the modern world. They include the magnetic compass, paddlewheel boats, canal locks, and segmental arch bridges. Some essential questions you may have will be answered throughout our presentation. To start off, the first Chinese compasses were pieces of a magnetic mineral called lodestone. When a piece of loadstone is placed on wood and put in a bowl of water, the lodestone will turn until it points in a north – south direction. Eventually, the Chinese developed a new compass that gave a more accurate reading. By rubbing a needle with lodestone it made the needle act the same way as the lodestone. The compass made long sea voyages possible because sailors could
In math class I would get my work done, then I would help students with questions that they didn’t understand. I like helping people that have trouble with the topics in math class. Math is my favorite subject. I like doing math in class and it’s one of the classes I do better than others. I really enjoy doing projects in math and science class. I especially like when we had to make our own rockets out of paper and tape. We even flew them. Also, we made a lava lamp. Well, in 6th grade I had math has my first block and that would cheer me up every single day in the morning. Those are some reasons why I want to be in the MST magnet program.
You can build a simple motor with magnet, wire, jumbo paper clips, sandpaper, neodymium magnets, and a compass. There are motors all over the place in your house. You use electric motors in your everyday life. When you connect the wires and connect it completes the current and makes the motor start. The copper wire will start to spin when the current is completed. I am build a simple motor and see if it spins slower or faster with bigger and smaller batteries I think it will spin faster with bigger batteries.
Before 1873, electricity and magnetic were two different forces until James Clerk Maxwell stated that the two forces interacted with each other. Scientist Alazen discovered that light does not originate from our eyes but is picked up from light that falls into them. Most objects do not emit their own light but reflect it. Light particles are not actually particles but
The economy during the Renaissance was a very price able period that allowed people to sell their own products on the streets and make their own profits. The tools that had developed in the Middle Ages for the exploration is used during the Renaissance period (Wilde). One of the tools is called an astrolabe that is a portable device that is used by the sailors to help them find their way home. They are often used by measuring the distance of the sun and the stars above the horizon, the astrolabes helped them determine the latitude and longitude, and it’s an important tool that helped the sailors navigate their way back to shore. The magnetic compass was also one of the inventions that were invented in the 12th century but was improved during the Renaissance period (Thompson 167).
What role do magnets play in the world we live? Learning Objectives: Students will know that
This was developed further in the 11th century with the Ancient Chinese creation of tiny magnetised needles of steel, one end points south and one end points north, it was the first compass. The compass was very important in naval navigation, before the compass there were no reference points in the ocean so if someone even turned a tenth of a degree in the wrong direction the could end up going hundreds or even thousands of kilometres off their target, the compass gave them a reference point and meant that it was much easier to
“The Earth's geomagnetic field is a combination of several magnetic fields generated by various sources superimposing on each other.” According to the Hong Kong Observatory. It says that “more than 90% of the field is generated by the movement of conducting material inside the Earth's core, which is often referred to as the Main Field”. The Geomagnetic field is used to explore the Earth’s inner core and the environment.
Next, we observed magnetism. Magnetism is a force that can attract or repel objects that have a magnetic material inside them. We measured
Since the compass was used to determine direction, it ignited the Age of Discovery. It also fueled the Industrial Revolution. The compass was first invented in 206 B.C. by China, by which it was later used for divination and geomancy for centuries. Without the compass, the world would have no understanding of magnetism. Magnetism is used in all kind of technological
A magnetic bearing is a type of bearing that holds up a load using magnetic levitation. Scientists first discovered the magnetic effects in magnetic minerals in 500B.C. In the late 20th century, scientists began developing ways where this magnetic effect could be implemented into a bearing, creating magnetic bearings. Today, magnetic bearings can be found in many applications where no physical contact is required or extreme environmental conditions exists, including very high and low temperatures. Magnetic bearings also offer higher running speeds, efficiency, longer machine life and lower operating and maintenance costs due to being virtually maintenance free.
