An electromagnetic force is stated to be induced when the flux linking with a conductor or change of coil. These changes can be seen in two different way namely statically or dynamically induced EMF. Statically induced EMF is generating by keeping the coil and magnetic field system and both of them are stable at the … Read more
Current Loop as AMagnetic Dipole and its Magnetic Dipole Moment Magnetic Dipole When two opposing and equal magnetic poles are separated by a small distance then it is said to be magnetic dipole. Whereas the magnetic dipole moment of the magnetic dipole can be defined as strength as the pole and magnetic length, the magnetic … Read more
Lenz’s law simply stated that the direction of the current running in the conductor by changing its magnetic field such that the magnetic field created bythe induced current which opposes the initial changing the magnetic field which is produced by it. Lenz’s law is mainly based on Faraday’s law of induction as Faraday’s law states … Read more
Faraday’s law This is a basic law of electromagnetism predicting how a magnetic field can interact to an electric circuit which can produce electromotive field derived as EMF and this phenomena is called electromagnetic induction and briefly this law can be named a Faraday’s law of induction. Many types of electrical motors such as transformers, … Read more
According to the atomic model of Niel Bohar, the electrons which are having negative charge are revolving around the nucleus of an atom that is positively charged. This movement is in the circular orbit having the radius r. The revolving of electrons is in the closed path that constitutes the electric current. If the motion … Read more
Foucault’s current is also known as eddy current which are loops of electric current induced within conductors by changing magnetic field in conductor according to Faraday’s law of induction. When there is a discussion about eddy current first thing mentioned is that it flows in closed loop within the conductor in planes perpendicular to the … Read more
Magnetic Field Intensity Due to AMagnetic Dipole (bar magnet) Along its Axis and Perpendicular to its Axis In physics the magnetic field intensity is also called as magnetic field strength. The magnetic field is created by the current-carrying wires. According to the law of Biot-Sarvat, the magnetic field at any point due to the element … Read more
For understanding how the bar magnet is becoming equivalent to the solenoid, it is extremely important to understand the bar magnet and solenoid and the similarities and differences between them. The bar magnet is a rectangular or square piece of an object that is made from iron or steel that is having permanent magnetic properties … Read more
Terms like self and mutual induction come from inductance. Inductance is a tendency in electromagnetism and electronics in which an electrical conductor opposed a change in the electric current following through it as the flow of electric current creates a magnetic field around the conductor whose strength depends upon the magnitude of the current. Electromagnetic … Read more
Diamagnetic Substances These substances are weakly magnetized, when they are placed in the external magnetic field, in a direction that is opposite to the applied field. The magnetism that is exhibited by these substances is known as the diamagnetism. The examples of these substances are silver, bismuth, gold, copper, mercury, lead, air, water, nitrogen, hydrogen, … Read more
