Magnetic flux

two circuits. The value of the coupling capacitance decreases with increasing separation of the circuits. Inductive coupling on the other hand is caused by mutual inductance between two conductors. When current flows through wires it produces a magnetic flux, which can induce a current in adjacent circuits. The geometry of the conductors as well as the separation between them determines the value of the mutual inductance, and hence the degree of the inductive coupling. Typically, capacitive…

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…

Monday, the start of yet another school day. Another day where he 's absent. Another day not learning anything. Another day where he won 't see and talk to his friends again. The opened window brought in cool air, swirling around the average hospital room. Unfortunately, this made the eleven-year-old boy shiver nonstop and his teeth clattering like a skeleton would. His front bangs of his silver-dyed hair brushed upwards, for the air sometimes liked to mess around with it, showing the child 's…

Electricity wasn’t invented it is already occurred in the nature. It was just discovered by Benjamin Franklin. His experiments (famous kite experiment) helped in building the connection between the electricity and lightning. In his experiment with kite included a kite with the key tie to the end of kite, which is connected to the Leyden jar. When the lighting struck the kite, the electric current travel down the string through the key and into the Leyden jar. We wonder that “what is there in…

1. Existing Knowledge- Based on prior knowledge, the Sulfur and Iron powder can be separated by using a magnet. The known fact is that the Iron particles can be attracted to the Magnet because of the attraction of the opposite charges. The Magnet will pull and attract the Iron and leaving the Sulfur behind. The separation of Sulfur and Iron powder is successfully accomplished because of the property of attraction. Since Iron is a metal, it has a positive charge and one side of the magnet has a…

are discovering the reasons why they exist. Many believe that the reason these lights are not seen during the day is due to the strong radiation that’s given out through the day. These auroras are caused by charged particles that collide with the magnetic atmosphere. At first glance the aurora looks to be light in colour but the substorm after the first glow is a lot brighter and has a much darker colour. Yusuke Ebihara is a physicist from Japan who has been studying these northern lights. He…

generators create electrical energy by creating a changing magnetic field. This works by moving a copper coil in a permanent magnetic field. The induced field created in the copper coil opposes the permanent one (according to Lenz's Law). These two opposing magnetic fields create the force that resists the rotation of the coils. When the light bulb is taken out no current can flow through the coil (Faraday's Law) so no opposing magnetic field is created. Hot Plate Why didn’t the power you…

In this report I will explain how a motor works. Fig. 1 shows the parts of the motor. In this motor, there are two field magnets on each side coil with wire. These two field magnets always have opposite polarity. On the middle of the motor there is an armature, two commutators and two brushes. When current flow though the two brushes, one of the brushes touches commutator plate 1 and the other brushes touches commutator plate 2. Then the armature A and armature B turn in to field magnets,…

Magnetic therapy or magnet healing is a type of alternative medicine that have magnetic fields that generates healing powers towards a large number of diseases or conditions. These electromagnetic fields have been demonstrated to treat slow-healing fractures in the body and have shown good results towards to a few conditions. The website that has claimed to use this magnetic therapy are Skepdic.com. The claim that this complementary and alternative medicine practitioner is making goes…

Hannah Baker, from a white picket fence town with an almost perfect family, committed suicide. From being raped by a popular boy, to witnessing her friend's sexual assault, to her best friends turning their backs on her, Hannah endured countless acts of bullying, which she chronicles on 13 audio tapes that are passed around to her friends after her death. On the show, which was produced by Selena Gomez, we witness Hannah's friend, Clay Jensen, helplessly wish he had known what she was facing, so…
