Magnetic fields are everywhere. With this invisible force, they enable us to find our way, power circuits and communicate wireless, but they have some weakness. Having magnetic interference can cause huge problems.
Magnetic fields generate electric currents in conductors as they pass through. On one hand, this enables many of the antenna-bearing devices we rely on to function properly. On the other hand, this phenomenon also enables interference that can cause massive malfunctions or even equipment damage in the same devices. Magnetic field shielding is a fundamental part of commercial building design, incorporated labs, schools, offices and factories.
There are many forms of magnetic field shielding. Such as, The Coaxial Cables On Television system and internet lines implement their own internal shielding. These wires needs their signals to travel over several miles of wire without changing beyond a specific amount, If a strong magnetic field induces noise into the signal, the data it carries will be corrupted by the transformation. Magnetically shielded wiring includes an individual layer of foil that encloses the conductor inside it completely. This foil shielding is itself conductive enough that any electric interference current created by an unwanted magnetic field is dissipated there before reaching the actual signal wire. Cell phones and other devices with sensitive components employ loose metal cages that serve the same function, enclosing everything but the antenna.
The design that magnetic shielding follows has the same plan in commercial application. By creating a conductive metallic cage around a room, usually inside the walls, floor, ceiling and doors, engineers can easily block out unwanted magnetic fields. This very technique has several integral applications.
Many commercial research and development labs operate test equipment that requires good magnetic shielding. The results could be biased when they generate false signals in the presence of a wayward magnetic fields.
Shielding is also used in the hospital. The magnetic resonance imaging (MRI), patient monitors and ultrasound machines all can distinguish signals that are so small compared to the noise of present background radiation. The patient’s safety and health all depends on these facilities’ ability to uphold a magnetic field free environment. The same goes to air traffic control towers where cell phones are distractions.
There are some health situations that magnetic fields are most hazardous. Strong fields can cause many health effects, though there is no evidence that explains this. The most evident among these is the fact that a strong field can create high currents and accompanying sparks that start fires or deliver painful shocks. That is why power stations incorporate shielding.
Magnetic field shielding is more important than you think. Whether you’re doing research, healing patients, or operating communications relays, your work relies on incorruptibly perfect signals and clean data. Incorporating magnetic shielding design in your building is the best way to ensure your results are accurate and entirely error-free.
