An Electromagnetism electromagnetic cavity is a cavity that acts as a container for electromagnetic field s such as photon s, in effect containing their wave function inside. The size of the cavity determines the maximum photon wave length that can be trapped. Additionally, it produces quantized energy level s for trapped charged particles like electrons and protons . The earth s magnetic field in effect places the earth in an electromagnetic cavity. Physical description of electromagnetic cavities Electromagnetic cavities are represented by potential well s, also called boxes , which can be of limited or unlimited depth V sub 0 sub . Quantum mechanic boxes are described by the time independent Schr dinger equation div align center math left frac hbar 2 2m nabla 2 V mathbf r right psi mathbf r E psi mathbf r math div with the additional boundary condition s the wave function is confined to the box infinite deep potential well or approaches zero as the distance from the wall increases to infinity, thus normalisable the wave function must be continuous function continuous the derivative of the wave function must be continuous which leads to real solutions for the wave functions if the net energy of the particle is negative., i.e. if the particle is in a bound state . Applications of electromagnetic cavities Electrons which are trapped in an electromagnetic cavity are in a bound state and thus organise themselves as they do in a regular atom , thus expressing chemical like behaviour. Several researchers have proposed to develop programmable matter by varying the number of trapped electrons in those cavities. http www.wired.com wired archive 9.10 atoms.html The discrete energy levels of electromagnetic cavities are exploited to produce photons of desired frequencies and thus are essential for nano or submicrometre scale laser devices.

Electromagnetic Testing ET , as a form of nondestructive testing , is the process of inducing electric current s or magnetic field s or both inside a test object and observing the electromagnetism electromagnetic response. If the test is set up properly, a defect inside the test object creates a measurable response. The term Electromagnetic Testing is often intended to mean simply Eddy Current Testing ECT . However with an expanding number of electromagnetic and magnetic test methods, Electromagnetic Testing is more often used to mean the whole class of electromagnetic test methods, of which Eddy Current Testing is just one. Common Methods of Electromagnetic Testing Eddy Current Testing ECT is used to detect near surface cracks and corrosion in metallic objects such as tubes and aircraft fuselage and structures. ECT is more commonly applied to nonferromagnetic materials, since in ferromagnetic materials the skin effect depth of penetration is relatively small. Remote field testing RFT is used for nondestructive testing NDT of steel tubes and pipes. Magnetic flux leakage Magnetic flux leakage testing MFL is also used for nondestructive testing NDT of steel tubes and pipes. At present RFT is more commonly used in small diameter tubes and MFL in larger diameter pipes over long travel distances. Wire rope testing is MFL applied to steel cables, to detect broken strands of wire. Magnetic particle inspection MT or MPI is a form of MFL where small magnetic particles in the form of a powder or liquid are sprayed on the magnetized steel test object and gather at surface breaking cracks.

Electromagnetic Diaphragm is a form of capacitive sensor used on an electronic stethoscope . The diaphragm is coated with a Electric conduction conductive material . Behind the diaphragm, a conductive plate is positioned behind and parallel to the diaphragm, so that the two conductive elements form a capacitor . Capacitance is a function of plate area, dielectric properties of the space between the conductors, and the distance between the conductors. It is this latter parameter which is modulated by vibration such that the capacitance varies with the distance between the Electromagnetism electromagnetic diaphragm and the plate, forming an acoustic sensor. ref name Thinklabs cite web url http www.thinklabsmedical.com electronic stethoscope technology electromagnetic diaphragm emd 102.html title Electromagnetic Diaphragm EmD publisher thinklabsmedical.com work Thinklabs accessdate June 04, 2011 ref The electromagnetic diaphragm is a form of capacitive sensor, and shares properties with condenser microphone s.
