Effects of EMFs on equipment

From: EMFs.info

Note from Multerland-Admin: please realize that your heart, brain, your body’s organs, systems, are more sensitive to EMF, than any artificial “organ”, “system”, named equipment, and that the impact of EMF on your organs and systems is severe, that wireless radiation creates harm, mostly irreparable harm. The Big Media, even most of the general practitioners, doctors, surgeons, nurses, consider EMF to be safe, because the ICNIRP guidelines decisionmakers say EMF is safe. This is a pertinent lie: page with 56 chapters about the immorality of ICNIRP. Please inform yourself with the evidence based facts of neutral / independent science: EMF-links, plus the blog posts published from 2019 till the present. See: archives.

If you would like to know how high the EMF levels are in your house, street, your children’s school, the playground, supermarket, library, etc. I recommend the EMFields Acousticom2 [video]. Not cheap, but the cheapest of all reliable calibrated devices. You will be shocked, and warned. It is possible to avoid wireless radiation, by using ethernet cables, and disabling Wi-Fi, not only in the router, but in every wireless device in the house. It is turned on by default. More videos about EMF radiation in the house, streets, railway stations, etc.:

1. The Electromagnetic Spectrum (NASA, 2010) – video
2. Something is in the air: the cellphone documentary (2021)- video

Graphic: increasing total of cellphone users, so: the increasing of EMF exposure, affecting also not-cellphone-users, foetuses, babies, toddlers, children, ill people, healthy people, birds, bees[video Daniel Favre], plants, trees, animals, fish, water….

Effects of EMFs on equipment

There are several types of equipment that can be affected by fields. However, the fields required are usually rather higher than those commonly encountered in the environment.

  • Credit cards, railway tickets etc have information encoded on a magnetic strip. This can be corrupted by magnetic fields above about 10,000 µT. Such fields almost never occur at 50 Hz, but a problem can arise with static fields such as those from magnetic catches on handbags.
  • Some cars with electronic control systems have been found to be susceptible to interference from power-frequency magnetic fields above about 2,000 µT. Again, such fields are rare at 50 Hz. This tends to be more of a problem at higher frequencies.
  • There are occasional reports of car batteries draining under overhead lines, but if this happens, it is just coincidence – there is no way for the field levels under an overhead line to affect the chemistry of batteries or the drain on them from other equipment in the vehicle.
  • There is no direct effect of EMFs on bicycles but riding a bicycle under a high-voltage power line can produce a microshock.
  • Quartz watches with analogue dials use a small stepper motor to drive the hands. This stepper motor can be driven by a suitably oriented external power-frequency magnetic field of about 1000 µT or greater, causing the hands to rotate 100 or more times faster than normal. The effect is spectacular but has not been found to cause any damage to the watch.
  • Power-frequency electric and magnetic fields constitute a possible source of interference with the operation of some types of implanted cardiac pacemakers or other active implants. [Continue reading below the picture.]

  • Interference is a well-known issue with some other sources of EMFs – shop security devices, some DIY power tools, etc –  but there has been no recorded case in Britain of a patient coming to any harm as a result of fields produced by the power system. The UK Department of Health, Medicines and Healthcare products Regulatory Agency (MHRA), does not consider that transmission-line electric or magnetic fields constitute a significant hazard.Most pacemakers are designed to ‘fail safe’ by reverting to fixed-rate operation when they sense the presence of interference above a certain level. The field strengths necessary to induce such behaviour vary from one pacemaker model to another but are generally higher than the fields encountered in the environment.  More detail on EMFs and implanted medical devices.
  • Magnetic fields may, in some circumstances, affect the steadiness of the image on old-fashioned  visual display units (VDUs) which use cathode-ray tubes. Liquid-crystal, plasma and other modern display technologies are virtually immune from such problems, so this is increasingly a historical problem only. It occured if the frame frequency of the VDU is close to but different from the power frequency (50 Hz). The effect is to cause the image to wobble at a frequency which depends on the difference between the frame frequency and the power frequency. Some VDU models may typically be sensitive to fields of 0.5 microtesla.  Limited amelioration can be achieved by careful orientation of the VDU and by screening. Screening magnetic fields is, however, difficult; even using high-permeability alloys such as “mumetal”, worthwhile screening factors still require large amounts of the screening material. More on screening fields.
  • fluorescent tube works by an electric field inside the tube causing a discharge, and this electric field can come either, as normally, from applying a mains voltage across the tube, or from the electric field produced by a power line. So fluorescent tubes will produce a visible glow under a power line, though usually it is only visible after dark as it is much weaker than the light they normally produce. The current through a fluorescent tube under a power line would probably be 20 – 200 microamps (µA) depending on the field. This is much less than a person can normally perceive, so you can hold the tube yourself under the power line without it hurting. (For comparison, a 10 W tube at 230 V draws 40 mA – 200 times greater). You can sometimes also make a fluorescent tube produce visible flickers by holding one end and rubbing your foot on a carpet to generate static electricity, though again, this needs to be done in a dark room.
