1, magnet magnetic field damage: we will know the magnet magnetic field on the human body has functions of promoting blood circulation, temporarily no data to indicate the magnet magnetic field directly harm on human body, so don't worry about is too much for the magnet magnetic field.
2, to the magnetic field of have a harm to human body, size depends on the strength of the magnetic field, in general, 3000 gauss (
Magnetic field units)
The following magnets, no harm to human body, more than 3000 field strength magnets, there is a harm to human body.
Magnet while harmful to human body but someone afraid of negligible magnetic field affect the body, but according to the test, magnetic field effects on people is only one 5 of the television.
3, magnet direct harm to the human body: although the magnet magnetic field have no harm to human body, but the direct contact with the magnet itself may have to the person direct damage in the following kinds: (1), magnet directly on the suction can cause a task, it especially ndfeb strong magnet and large magnet of the task of harm to human body more.
(2), magnets by mouth to enter the body of the damage is more serious, life is likely to be hurt, because the magnet itself with magnetism, mutual absorption in the body can cause in vivo intestinal perforation, serious bleeding after, will endanger the life, please carefully magnets directly to the children to play.
