The process of how magnets repel each other causing levitation Magnets have always been a mystery. The curiosity of how the magnets attract or repel one another has always been a topic that scientists are deeply interested in discovering. Over the years, many scientists have made huge strides in the scientific world as to how magnets work. Magnets that repel one another can cause one of the magnets to levitate over the other. 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

If a magnet is near a superconductor, it will repel the other because the supercurrents reflect the charge of the poles. Superconductors are defined as, “An element or metallic alloy which, when cooled to near absolute zero, dramatically lose all electrical resistance.” Superconductivity was discovered in 1911 by a Dutch physicist, Heike Kamerlingh Onnes. This discovery won him a Nobel Prize in physics in 1913. Many Nobel Prizes have been awarded to various scientists since superconductivity was discovered. Superconductors can show signs of the Meissner effect; the Meissner effect causes all magnetic instability inside the element to change. When this happens, the lines around the magnetic field will orbit the superconductor. The properties of superconductors are used in scientific experiments. (Zimmerman, 2015) If a permanent magnet is located beyond a superconductor, it can cause an illusion of levitation by this force. Levitation currents caused by the superconductor will produce actual magnetic poles to repel and support the magnets. (Magnetic Levitation,

The first magnets were pieces of lodestone. The Chinese later replaced lodestone with the iron needle, which was much more accurate than lodestone. They had learned that rubbing a steel needle with lodestone made the needle magnetic. By the Song dynasty, the use of the magnetic compass had grown to include the sea voyages.
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.

for so long unexplained and although there has been a lot of progress in figuring out how magnetism works and what it’s caused by, it still isn’t completely understood. There are many theories about magnetism, but there is still much more yet to be discovered about magnetism. In the future it will probably be easily understood, but none the less intriguing.
The idea behind the “Mozart Effect” is that when babies listen to classical masterpieces, specifically Mozart, their brainpower will be enhanced which ultimately increases their intelligence. There are a myriad number of people who have tested this hypothesis and truly believe that the waves and the sounds engenders cognitive skills in the domain of learning. However, the real question is that do scientists substantiate this claim? Is there solid evidence or is it all an obscure hypothesis?
Field line patterns exist within a magnetic field that is created by a current. These field lines of a coil or a solenoid can be traced by using a compass because they create a dipole pattern, meaning that they diverge from the north end and
Maglev means magnetic and levitation (Liu; Long; Li 1). “Maglev is the method of propulsion that uses magnetic levitation to propel vehicles with magnets rather than with wheel, axles, and bearings (Liu; Long; Li 1). They are levitated a short distance away from the guideway by using magnets to create both lift and thrust (Liu; Long; Li 1). They don’t have friction means that acceleration and deceleration that can exceed that of wheeled transports and are protected from weather (Liu; Long; Li 1). “Maglev promises to be a major mode of transport
What is magnetism? When two pieces of iron are attracted to each other by physical means or electrical means.
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.
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.
In the early 1900's a duch physicist by the name of Heike Kammerlingh Onnes (pictured above), discovered superconductivity. Before his discovery, Onnes had spent most of his scientific career studying extreme cold. The first step he took toward superconductivity was on July 10, 1908 when he liquified helium and cooled it to an astonishing 4 K, which is roughly the temperature of the background radiation in open space. Using this liquid helium, Onnes began experimenting with other materials and their properties when subjected to intense cold. In 1911, he began his research on the electrical properties of these same materials. It was known to Onnes that as materials, particularly metals, cooled, they exhibited less and less resistance. Bringing a mercury wire to as close to absolute zero as possible, Onnes observed that as the temperature dropped, so to did the resistance, until 4.2 K was reached. There resistance vanished and current flowed through the wire unhindered. Below is an approximate graph displaying resistance as a function of temperature for the experiment Onnes conducted with mercury:
The most obvious way Levitation can be performed is by raising something up, but there are many other ways that Levitation can also be performed like Magnetic Levitation can be used for melting different things or for maglev train. A Maglev train is a public transport technology that uses electric levitation to move vehicles with making contact with the ground or an electrical pickup. Although Magicians are the most well known people to perform levitation the are not the only ones to know how to use it. For many years, NASA scientists have used superconducting magnets to levitate insects, frogs, and mice. There are many ways that Magnetic Levitation can shape the future. Some examples are flying cars, magnetic bearings, and Studying weightlessness. I believe that Levitation is real and that it can be performed for a number of reasons. My first reason is that it has been proven that levitation can be Performed because NASA made crickets and other insects levitate before. My second reason is if levitation really was fake wouldn’t people have already found it out about it and proved that
