Electro-magnetism

For the case of electro-magnets, inclusions detection in welds situated at 1-2 mm of depth is very important, because the reluctance variation between the two mediums is not important, and thus the detection of this type of defect is very difficult. It will be sufficient to be in optimal conditions to eliminate this problem. 

Electro-magnetic emission in the radiowave range is for long period of time used for water basins diagnostics. 

Conventional covermeters operating on the principle of electro-magnetic fields are capable of determining depth of cover to reinforcement down to about 100 mm with an accuracy of 5 % provided the bar diameter is known and the spacing between individual bars is greater than about 150 mm. If bars are spliced then the covermeter will underestimate the cover depth.

A strong electro-magnetic field, such as that generated by large mill motors, accelerates cable oscillation. In these instances, the vibration generated by the cable will mask real machine vibration. 

The correctness of this statement is to be inferred from the exact agreement between the values of the mechanical equivalent of heat obtained by different methods. Thus, in Joule s second series of experiments, mechanical work is directly converted into heat in the first and third series, it is indirectly transformed through the medium of electro-magnetic energy in the fourth series, the energy of an electric current is converted into heat the identity of the values of J so obtained implies a complete conversion of the initial forms of energy into heat energy.

A fourth possibility is electrodynamic bonding. This arises because atoms and molecules are not static, but are dynamically polarizable into dipoles. Each dipole oscillates, sending out an electromagnetic field which interacts with other nearby dipoles causing them to oscillate. As the dipoles exchange electro-magnetic energy (photons), they attract one another (London, 1937).

Hamiltonian quantum states. Two situations can be envisaged. In the first one, the system moves stepwise from the APC states to the interconversion complex. We assume that the i-th state of the active precursor is populated i f > at a given time to, and if f> is intermediate Hamiltonian state that are coupled by the electro-magnetic field.

The word radiant energy is the energy transmitted from one body to another in the form of radiations. This energy has wave nature and because it is associated with electric and magnetic fields, it is also called electro-magnetic radiations. The visible light, ultraviolet, infrared, X-rays, radio-waves and microwaves are all different forms of electromagnetic radiations. 

Some polyatomic molecules like C02 CS2 or SnCl4 which do not possess a permanent dipole, but develop a fluctuating dipole due to certain modes of vibrations also respond to infrared region of electro magnetic radiation.
