Magnetic field around two separated magnetising coils

International Journal of Materials and Product Technology (IJMPT), Vol. 27, No. 3/4, 2006

Abstract: If the arrangement of coils with the eddy currents testing is not a standard one it is very important to understand the physical principles of the new one to be able to interpret the results properly. A very useful tool for this purpose is the mathematical treatment of field equations. The numerical methods are often applied, since Maxwell equations are rather complex partial differential equations and there are usually real and imaginary components of the field to be taken into account. In this article there are basic algorithms given that are used with the method of finite differences. There are only main ideas given as to how to solve more complicated problems. The actual concrete results are part of a broader project and will be published later.
