Non-union following long bone fractures is a cause of significant morbidity to the patient. The management of this condition has proved difficult for the orthopaedic surgeon. Much research has been carried out on the use of electromagnetic stimulation in the healing of non-union. The objective of...
Electromagnetism is the type of magnetism produced by an electric current. This phenomenon was discovered by a Danish scientist named Hans Oersted in 1819.
Types of electromagnetic interference In EMI there is a source, a path and a receptor (or victim). There are several types of paths, or methods of transmission of EMI from the source to the receptor. Radiated EMIhappens when a high-power transmitter or electrical device produces aradio freque...
The EM Spectrum:The electromagnetic, or EM, spectrum is a range of electromagnetic radiation that goes from the lowest wavelength on the spectrum to the highest. The lowest frequency EM is radio waves, with their long wavelengths, and the highest frequency EM is gamma rays, which are very ...
Suppose that the electric field part of an electromagnetic wave in vacuum is E=(3.1N/C)cos[(1.8rad/m)y+(5.4×106rad/s)t]^i(a) What is the direction of propagation?(b) What is the wavelength λ ?(c) What is the frequency v?(d) What is the amplitude of the magnetic field part...
Where would you rather do your work: a nice coffeehouse or a busy office More and more, people are able to do their work with a good cup of coffee in the friendly environment of their local coffeehouse. With a powerful laptop and a mobile phone, it isn’t necessary to be tied to...
is the research that under the conditions of limited space, limited time, and limited spectrum resources. A science in which various electrical equipment (subsystems, systems; in a broad sense, organisms) can coexist without causing degradation. Electromagnetic compatibility consists of the following ...
