Magnetism Essay

William gilbert was an astronomer, English physician, and a physicist. Also know as the”father of electricity”. His parents were Hierome Gilbert and Jerome Gilbert. He had four books published in his lifetime which one of them were about how he did his experiments and all of his findings about the earth and its magnetic forces. William Gilbert was born May 24, 1544 in Colchester, England. He went to St John’s college and Cambridge University he later gained a MD from the St John’s college, Cambridge

This week 's math and science lesson focused on magnetism and incorporated both math and science standards, per the Arizona Early Learning Standards. The lesson started with reading a book regarding magnetism, entitled What Makes a Magnet? by Franklyn M. Branley. After the read aloud, students were dismissed for centers and groups of five students circulated through completing the lesson activity. For this lesson, the objective and sub-objectives were as follows: • After completing this lesson, students

between each loop could also affect the the strength and the time the the nail would hold the metal objects. Background research The purpose of this experiment is to prove if the number of wires wrap around the nail will affect the strength of magnetism. The electromagnets are used in many household items. Electromagnets are Magnets when they have electricity running through them, but they are not regular magnets because electromagnets can be turned on and off, so when when electricity

Abstract Summary 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. Magnets also has North and South poles which can flip. The amount of magnetic material attracted to the magnet, allows the magnet’s poles to flip. Flipping on the earth’s magnet could cause destruction on the earth. The magnetic field protects earth from solar radiation. Purpose of the

field protects the Earth from space radiation and particles. Contrary to popular belief the magnetic field strength of an object is based on the material that the object is made of and not the mass of the object. Previously scientists believed magnetism and electricity were two separate forces but in 1820 Hans Christian Orsted observed that when he turned on a battery that had electric current flowing a compass needle moves away from north. This experiment showed him that electric current flowing

1. Bar magnet is the simplest form to explain magnetism. Bar magnets are permanent magnets and this means that they have magnetism all the time, it can’t be turned on and it can’t be switched off. They have two poles that include: north-seeking pole (N) and south-seeking pole (S). These poles appear to occur in equal and opposite pair. Magnetic meridian is the vertical plane in which the magnet lies. Magnets are made of materials that can be magnetized, which are also the ones that can be attracted

electricity and magnetism made possible the invention of the electric motor” (Electric Motors, 2008). Without one or more fixed magnets combined with a movable current-carrying coil, electric motors will not run. Pinball machines, paintball markers, dot matrix printers and fuel injectors in vehicles all use magnets by means of electromechanical solenoids. A solenoid is “a tightly wound helix of current-carrying wire (which) acts like a hollow bar magnet” (Electricity and Magnetism,

simple DC motor were a power supply is used to power the motor to start to spin unlike some other motors like in cars where they rely on all other forms of injections for it to power such a large object. An el­ectric motor is all about magnets and magnetism: A motor uses magnets to create motion. Electric motors involve rotating coils of wire which are driven by the magnetic force exerted by a magnetic field on an electric current. They transform electrical energy into mechanical energy (Internet 1)

Written Report Concerning Rocket Sled Catchment Arresting Systems   QinetiQ, a defence technology company headquartered in Farnborough, have a problem regarding their Pendine long test track facility located in South Wales. The test track is 1500m long and test items are powered down the track on sleds pushed by rocket motors. QinetiQ are finding a variety of engineering challenges in containing the rocket motor sleds in relatively short distances at the end of the track on high velocity trials (600m/s

Magnetic Levitation Trains "Magnetic Levitation Trains, why should they be implemented in the United States?" Whenever individuals talk about trains, a few ideas pop into one’s mind. These include the railway tracks that provide runways for the wheels, the noise associated with them and the long heavy carriages that they pull. Utilizing the words ‘Magnetic Levitation’ in relation to trains may seem like a peculiar idea. Why? Levitation can be described as the act of raising an object upward in
