Electromagnetism

The most commonly used and widespread method of detecting the magnetic field is the Hall effect method among the various sensing technologies Based on the

In general magnetostatic fields are produced by the motion of electric charges with uniform velocity whereas electrostatic fields are produced by the stationary charges On

In contrast to the electrostatics which deals with static electric charges also called Coulombian approach magneto statics deals with stationary electric currents also called Amperian

In this 21st century MEMS technology has been showing its potential to revolutionize consumer as well as the industrial products by combining silicon based microelectronics

According to Maxwell s equations electromagnetic fields are produced or created by the time varying sources such as currents and charges If these fields are

Waves are omnipresent in nature that transfers the energy or information from source to destination The wave is a function of both space and time

Actuators convert a given kind of energy into mechanical energy There are different classes of actuators depending on the physical principle on which the energy
