Electromagnetic designs are observed in the large range of industrial and R and D applications such as cables, magnetic shielding, transmission lines, large voltage systems and various EM units. Engineers require to evaluate the electromagnetic nature of fields, forces, currents etc of these systems to manage their cost and functionality efficiently. Earlier engineers were only bounded to expensive prototyping or controlled analytical models. But in the modern time, they use electromagnetic computerized engineering software tools to offer economical design solutions.
The magnetic shielding mesh is used in the internal design structural walls of the electronic systems that are an economical solution to use and provide excellent shielding from the electromagnetic radiation.
History of magnetic shielding
The ideal application of magnetic shielding was in nuclear magnetic resonance (NMR) units. The imaging of NMR is a significant part of the radiologist suite of imaging methods and it needs extremely uniform magnetic field. A large solenoid with high current density of 15,000 – 20,000 A/cm2 is utilized to develop the required magnetic field. Considering the current density H on coils in space, the radial and axial extent can be found numerically. The design problems occurred due to line’s special area from 1-m hot bore superconducting magnet that influences other crucial hospital area. The magnetic shielding is utilized to decrease the fringe field of 15,000 G magnet to 3,000 G hence making consecutive hospital rooms more significant for other radiological applications. The factors considered while designing the shielding material are: % G radial and axial level, homogenous magnet and shield’s specification
