FUSE THEORY The energy conversion process is carried out with the help of magnetic fields. These conversion processes also result in losses to the machine. Types of Losses The losses in a three phase induction machine are broadly classified into the following types 1) Magnetic losses 2) Electrical Losses 3) Mechanical Losses Magnetic losses The presence of rotating magnetic field in the stator core results in the magnetic losses. Stator core is made up of silicon steel or iron stampings‚ these losses

1.1 RFID Radio-frequency identification (RFID) is the wireless use of electromagnetic fields to transfer data‚ for the purposes of automatically identifying and tracking tags attached to objects. The tags contain electronically stored information. Some tags are powered by electromagnetic induction from magnetic fields produced near the reader. Some types collect energy from the interrogating radio waves and act as a passive transponder. Other types have

process includes a test coil through which vary or alternating current (AC) is passed. 3. A varying current flowing in a test coil produces a varying electromagnetic field around the coil‚ As shown in this diagram Amperage * # of coils= strength of magnetic field 4. The electromagnetic field produced around the coils is directly proportional to the magnitude of applied current‚ rate of change in current or frequency and the coil parameters. 5. Coil parameters

March 15‚ 2012 Conclusion: This experiment clearly demonstrated how Ampere’s Law relates the magnetic field to the current using the relationships stated in the formula B= μ0I2πr. This relationship allowed to the experiment to calculate the value of permeability of free space in order to verify the relationship that is outlined in Ampere’s Law. This lab also allowed us to measure magnetic field strength as a function of the distance measured perpendicularly from a long current-carrying wire

The computational domain is simply the physical region over which the simulation will be performed. The E and H fields are determined at every point in space within that computational domain. The material of each cell within the computational domain must be specified. Typically‚ the material is either free-space (air)‚ metal‚ or dielectric. Any material can be used

physics‚ the term solenoid refers to a long‚ thin loop of wire‚ often wrapped around a metallic core‚ which produces a magnetic field when an electric current is passed through it. Solenoids are important because they can create controlled magnetic fields and can be used as electromagnets. The term solenoid refers specifically to a magnet designed to produce a uniform magnetic field in a volume of space (where some experiment might be carried out). In engineering‚ the term solenoid may also refer

In this assignment‚ we are assign to construct a 2 button type Ac motor control system. The 2 type button means that there are only 2 buttons which is the stop button and the forward button. The successful build the whole system‚ a few component are very critical in this system. Circuit breaker First is the circuit breaker. Circuit breaker is a switch which is designed to prevent damaging the circuit when there is over load or short circuit. But the circuit breaker works differently compare

the University of Lyon just one year later. In 1809‚ Andre Ampere was appointed professor of mathematics at the Polytechnic school in Paris. He was admitted as a member of the Institute in 1814 and in 1820‚ after H.C. Orsted’s discovery that a magnetic needle is acted on by a voltaic current‚ Andre sent a paper of his own to the Academy that was much more detailed. He didn’t wait‚ on September 18‚ 1820‚ the very same day that he sent his paper‚ he presented a demonstration to the Academy that parallel
