Maxwell's equations still provide a complete and elegant description of electromagnetism down to, but not including, the subatomic scale. The interpretation of his work, however, was broadened in the 20th century. Einstein's special relativity theory merged electric and magnetic fields into one common field and limited the velocity of all …

The transverse flux permanent-magnet (PM) linear machine has attracted much attention in high-performance direct-drive applications because of its high torque density and efficiency. However, due to its inherent large open-circuit flux leakage, the prominent cogging force makes it difficult to obtain a high accuracy in position and speed control, which restricts …

In 1953 IBM Endicott, New York, announced the IBM 650 Magnetic Drum Data Processing Machine.This was the first mass-produced computer.Between 1953 and 1962 almost 2000 systems were produced. At this time IBM was reluctant to call the machine a computer, since that term was so closely associated with UNIVAC.

To create a radiograph, a patient is positioned so that the part of the body being imaged is located between an x-ray source and an x-ray detector. When the machine is turned on, x-rays travel through the body and are absorbed in different amounts by different tissues, depending on the radiological density of the tissues they pass through.

Magnetic Separation Process. The magnetic separation machine releases a current through the coil within the machine, creating a magnetic field. This, in turn, magnetizes the steel matrix inside the machine. As material flows through the magnetized matrix, all magnetic material is captured, and the non-magnetic material passes through.
