Powerful magnets Parallel Circuit Analysis Report a cylindrical drum, outside an annular powerful magnets, placed inside a circular iron (iron outer diameter approximately equal to the drum diameter), the ability to move up and down the outside by means of powerful magnets to drag move up and down movement inside iron circular iron plate theory you can overcome gravity and friction with the inner diameter drum on it. Static magnetic field is steady magnetic field generated by a current or permanent magnet. Static magnetic shielding is the use of high magnetic permeability μ shield made of ferromagnetic material in order to shield the external magnetic field. It is similar with electrostatic shielding and have a different role. However, to overcome the frictional force mentioned circular iron plate of gravity above the complex association. A child under desks desktop, powerful magnets to drag steel piece on the desktop to move magic. No gravity problem. Manufacturers answers harmless as a powerful magnet magnet manufacturers will often hear customers ask to various issues, trustworthy medical equipment magnet magnetic than the most common of your powerful magnets so strong, will the human body there is some damage to it? So the question we in the end how to answer it? I believe many of my friends want to know the damage a magnet for people in a high magnetic field are concentrated on human whether there is damage, this is mainly due to most of what we usually hear electromagnetic radiation, etc. words. The reason is also client puzzled, medical equipment magnet, here we come to resolve this issue specifically. First, we are strong magnets or high-strength magnets physical harm requires special attention. This is due to the particularly strong magnetic force of the magnet, and therefore we must prevent entrapment, such as blade will be stabbed in the hand to breathe more. Second, this is actually a lot of friends magnetic radiation concerns. And this as a powerful magnet manufacturers, and has not done related tests and trials, and this aspect is not the manufacturer's technical location, but a lot of relevant information consult our engineers point of view, are no relevant studies have shown that permanent magnets magnetic harmful to humans. And on the contrary, we can see a lot of products on the market today are based on magnetic health do for advertising keywords to attract consumers, showing a powerful magnet did not harmful to the human body, in addition we have special instructions referred to herein the powerful magnets or NdFeB magnets which material harmful to humans, other large unconventional is not necessarily harmless.
