Magnetism

two poles, called the north pole and the south pole. The two poles may look the same but they behave differently. Put one pole of a magnet near to a pole of another magnet, and watch what happens. You may feel an attraction (pulling) force as the two poles stick together. Alternatively, you may feel a repulsion (pushing) force, as the two poles push away from each other. In all magnets, identical poles will repel (push away) each other. In all magnets, identical poles will repel (push away) each other, while different poles will pull towards each other." Magnets can be many shapes and sizes but they all have the ability to pull things toward themselves. The invisible force that allows magnets to pull things toward themselves is called magnetism. Most magnets are usually made up of a material with lots of iron in it or just iron. Magnets also only pull objects that contain iron or just iron.

One way to think about it is like this: If you have a perfectly insulated room and you put an electric fan in it, then the room will get warmer. All the electricity that is driving the fan turns directly into heat. So a fan does not cool the room at all. What a fan does is creates a wind chill…

The article Cosmic Turbulence May Spawn Monster Magnetic Fields discusses a lab experiment that aimed to investigate the mysterious and powerful properties of magnetism in space. Magnetic waves are extremely prominent in our universe, which consists of dense galaxy clusters and vast voids of space separating these clusters. While it seems obvious magnetism would be present in the various galaxy clusters, as they are active regions of space, astronomers have also discovered a very strong magnetic…

the battery. Write your observations in your science notebook. Repeat the steps again, but this time wind the wire around the nail 20 times. Record your observations in your science notebook. Repeat the steps one more time, but this time wind the wire around the nail 30 times. Record your observations in your science notebook. When the experiment is done students will be able to understand that electric, and magnetic forces between a pair of objects does not require that the objects be in…

Oscar Padilla Oscar Padilla Oscar Padilla 11-13-17 Mr. McMahon Period 1 Magnetic field strengths My science project is about homemade electromagnetic magnets and permanent magnets strength on heat and cold temperatures. I'm going to accomplish this by making three sets of electromagnets and permanent magnets in hot temperature, room temperature and cold temperatures to see how would they be affected by the different temperatures its put in. But the dependent variable is on the…

electric current flowing through the coil will have little or no effect. Magnetic hysteresis loop shows the conduct of a ferromagnetic core graphically as the relationship between flux density (B) and field strength (H) is not linear. Both B an H will be at zero in magnetisation curve when starting with an unmagnetised core. As it goes towards saturation, if the magnetic current would be increased in a positive direction to some value, magnetic field strength (H) increases linearly with i and…

Diamagnetism can make levitation possible. How? Diamagnetic materials are repelled by magnetic fields. The most diamagnetic materials are graphite and bismuth. Technically, everything is diamagnetic but the force of it is very weak. Diamagnetism is present in everything, but is only observable if other types of magnetism, such as paramagnetism, ferromagnetism, ferrimagnetism, antiferromagnetism, etc. do not overwhelm it. Most of the time, diamagnetic materials’ effect is very weak. Levitating…

Magnets create magnetic fields, which can attract or repel metal objects. Magnets are utilized in motors, circuits, compasses, and can be used in many other applications. They are also used in something called the Gauss Rifle, which can use magnets to launch a projectile at high speed. It is made up of one or more magnet stages, which consists of a magnet and two ball bearings on one side. The number of magnet stages can determine how fast or how slow the projectile can go. It should be noted…

Essentially, people perpetually desire more - more space and more potential. Due to technological advancements, consumers are demanding higher quality electronics with larger capacities. Consequently, the technology of hard drives and computer memory software are vastly improving and have been introduced into society. The first hard drive was created in 1956 and was the size of two refrigerators. Now, in 2016, hard drives can be as small as 1 inch. These devices serve as the ‘brain’ or ‘memory…

MAGNETIZING WITH MAGNETO (small groups) Magneto is a superhero who can control metal. By tapping into the power of magnetism, an invisible force that pulls things together or pushes things apart, he can throw cars and move buildings all with the flick of a finger. The Earth itself also happens to be one big magnet, creating a magnetic field, or type of force field, that extends miles beneath the Earth’s surface and into space. Now, split campers into 8 groups of 3 or 4, giving each group two…

CHAPTER II. REVIEW OF THE RELATED LITERATURE A. Temporary Magnet Temporary magnets are those that essentially demonstration like permanent magnets when they are inside a strong magnetic field (Jezek, 2015). They are not like permanent magnets when it's not around in a magnetic field because it loses its own magnetism. Temporary magnets cannot remain magnetized on their own (Boyer 2017). Paperclips, press nails, and other comparative things are cases of temporary magnets. Temporary magnets are…
