The magnetic field, derived from the force field created by the movement of an electric charge, has a strength that is related to the strength of the magnet and the distance. It has a significant impact on human health and equipment performance. Prolonged exposure to high-intensity magnetic fields can lead to cellular wanderings, digestive problems and neurological issues, as well as affecting the proper functioning of equipment, such as scientific research and medical devices.
In everyday living and working environments, people are concerned about the suitability of magnetic fields. In general, magnetic field strength in homes and offices should be kept below 10 to 30nT, a range that is relatively safe for most people. However, specialized locations such as hospitals, laboratories, and MRI facilities need to have magnetic field strengths strictly controlled below 1 microtesla to safeguard equipment performance and personnel safety.
For environments where strong magnetic fields are present, regular magnetic field monitoring and control is essential and requires specialized equipment and technicians. At the same time, to protect the human body, protective measures may be required, such as the installation of lead or iron plates to reduce the magnetic field radiation. It is worth noting that although magnetic fields are different from electromagnetic radiation, there is an interaction between the two, so the effects of magnetic fields should not be ignored when assessing electromagnetic radiation.
In summary, the suitability of magnetic fields is critical to maintaining quality of life and equipment performance. In our daily lives, we should ensure that magnetic field strengths are within safe limits, while in professional environments, more stringent monitoring and protective measures are essential. This is as much about personal health as it is about the proper functioning of the equipment.
