Magnetic field

known as a hyperloop. Perhaps a more common use that is taken for granted is the magnetic…

The Physical Attraction Conducted in Magnetic Stove Tops Physics Around Campus Kendra Kritsonis Physics 102 Spring 2017 In this photo, a magnetic stove top is depicted. Pictured is the magnetic stove top with its multiple circular burners of many different sizes across the surface. This is the type of stove my family uses at our cabin. Summary: Most people use stove tops in their houses to cook meals. These days there are hundreds of stove options…

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…

When a magnet is in motion near a non-magnetic conductor such as copper and aluminium eddy currents are induced in the conductor, causing a dissipative force called magnetic braking force, or a change in magnetic flux (figure 2). This force is dependent on: The size and shape of the conductor and magnet The strength of the magnet (μ) The conductors conductivity (σ_c) The distance between the conductive surface and the magnet (d) The velocity of the magnet (v) According to Faraday’s law,…

variable frequency eddy current sorter (VFECS) prototype to separate different nonferrous metal and alloy of size smaller than 1 inches. VEFECS is a solid state technology which operates at variable high frequency range between 1 – 10 KHz. The magnetic field frequency plays an important role in sorting of different nonferrous metals and alloys from each…

Q. Why do wire and a compass work to detect electric currents? A. I’m going to start off with the basics here. A compass points north. Everyone knows that. Why does it point north? Well, all magnets have two “poles” or ends. One end of the magnet is called the north-seeking pole. The north-seeking pole is often abbreviated to north pole or the letter N. The north pole end of a magnet is usually colored red. The other end of a magnet is called the south-seeking pole. The south-seeking pole is…

efficiency of this transformer is largely dependable on the construction of its core. The iron from which the core is made has to be of a high permeability (amount of magnetization within the iron when immersed into a magnetic field) and a low retentivity (portion of residual magnetic field upon the removal of the magnetizing force). For the purpose of minimizing the energy losses, it is prefferable to use the straight core. The logic…

samples were also calculated which is known as squareness ratio. The materials having high value of coercivity show the hard magnetic materials and this behavior was observed in M-type hexa ferrites [36]. The measured values of coercivity ‘Hc’ for all the samples were observed in the range of (1.38-2.06) KOe. All the samples have high value of coercivity showing the hard magnetic behavior of M-type hexa…

(1) What is the hypothesis of this paper and where did you find it? The hypothesis of this paper predicts if low-intensity electric and magnetic fields (EMF) are a method of sensory transduction, then it is expected that that EMF can evoke brain potentials like other sensory modalities. This hypothesis can be found at the end of the Abstract and at the end of the second to last paragraph in the Introduction. (2) Is the writer’s voice passive or active and does he appear in the text? If the…

connected and better society. That thing is the human aura or the human energy field. This sort of feature that is inside of humans could lead to a better world for all of us and hopefully aid in the survival of humanity for years to come. This phenomenon called the human aura or energy field is a force field that wraps around the body and expands inside the body somewhat (Understanding the Human Aura and Human Energy Fields). It is created by cells and tissues that generate an…
