Electromagnetic Field Theory

Electromagnetic Field Theory

Electromagnetic is a branch of physics or electrical engineering in which electric and magnetic phenomenon studied. Electromagnetic (EM) may be regarded as the study of the interactions between electric charges at rest and in motion. Design: The design of EM devices include transformers, electric relays, radio/TV, telephones, electric motors, transmission lines, wave guides, antennas, optical fibers,… Continue reading Electromagnetic Field Theory

Magnetic Resonance Imaging (MRI)

Paramjeet Singh Jamwal Lecturer Guru Nanak Education Trust Group Of Institutions, Roorkee  --- "When Placed in a static magnetic field, certain atomic nuclei assume one of two states: one has a higher energy level and other one has a lower energy level. The energy difference between the two states is linearly proportional to the strength… Continue reading Magnetic Resonance Imaging (MRI)

Application of Electrostatics

Application of Electrostatics: Almost all computer peripheral devices, with the exception of magnetic memory, are based on electrostatic fields. Touch pads, capacitance keyboards, Cathode-Ray Tubes, Liquid Crystal Displays and Electrostatic Printers. In Medical work, diagnosis is often carried out with the aid of electrostatics, as incorporated in Electrocardiograms, Electroencephalograms and other recordings of the electrical… Continue reading Application of Electrostatics
