1, Magnetic field damage: We know that the magnet magnetic field on the human body will promote blood circulation, there is no information that the magnetic field of the magnet on the human body has a direct harm, so do not have too much concern about the magnetic field of the magnet.

2, the magnetic field on the human body is not harmful, depending on the strength of the magnetic field size, in general, 3000 Gauss (magnetic field unit) below the magnet, no harm to the human body, more than 3000 above the magnetic field strength of the magnet, It's Although harmful to the human body, the magnet is negligible. Some people fear that the magnetic field will affect the body. However, according to the test, the magnetic field has only one-fifth of the impact on the human body.

3, the magnet on the human body directly harm: Although the magnetic field of the magnet does not harm the human body, but the direct contact with the magnet itself may have the following direct human injury. 1, direct suction on the magnet may cause injury, which, in particular, NdFeB strong magnets and large magnets hurt the human body injury more. 2, the magnet into the body by the mouth of the more serious injuries, may be life-threatening, because the magnet itself with a magnetic, the body's internal absorption of each other will cause intestinal perforation, causing bleeding, the situation will be endangered Of life, please be careful magnet to play directly to the children.
