INTRODUCTION If an electric current flows through a conductor in a magnetic field‚ the magnetic field exerts a transverse force on the moving charge carrier which tends to push them to one side of the conductor. A buildup of charge at the sides of the conductors will balance this magnetic influence‚ producing a measurable voltage between the two sides of the conductor. This presence of measurable transverse voltage is the Hall Effect. The Hall effect was discovered in 1879 by Edwin Herbert Hall

that affect with electric and magnetic fields. The electromagnetic force is carried by the photon and is responsible for atomic structure‚ chemical reactions‚ the attractive and repulsive forces associated with electrical charge and magnetism‚ and all other electromagnetic phenomena. According to Coulomb’s Law‚ we know electric charges get Coulomb force in the electric field while current receives another applied force‚ which is Ampere force when it is in a magnetic field. Overall‚ electromagnetic

class of phenomena exhibited by a magnetic field. In physics there are a few types of magnetism. In this paper only three types will be covered which are ferromagnetism‚ paramagnetism‚ and diamagnetism. Ferromagnetism is considered the strongest type of magnetism‚ as it is a permanent magnet. A permanent magnet is one that remains a magnet after being magnetized by an outside magnetic field. Ferromagnetism is a type of magnetism that produces its own magnetic field that is what makes it unique

partly true‚ as the losses arising from magnetic leakage flux in various metal parts of a transformer constitute a significant part of the total losses. This component of total losses is called stray (additional) loss (Ps ). In addition‚ experts distinguish between the stray losses in the windings (winding eddy loss: eddy-current loss in conductors‚ and circulating-current loss in parallel strands) and outside the windings (stray 2 1 magnetic shield on the tank 2 yoke clamping

magnetic levitation magnetic levitation‚ maglev or magnetic suspension is a method by which an object is suspended with no support other than magnetic field. Magnetic pressure is used to counteract the effects of the gravitationa and any other accelerations. Earnshaw’s theorem proves that using only ferromagnetic or paramagnetic materials it is impossible to stably levitate against gravity‚ however‚ servomechanisms‚ the use of di magnetic materials‚ superconduction‚ or systems involving eddy currents
