1. Magnet magnetic field damage: we know that magnet magnetic field will promote blood circulation to the human body, there is no information that the magnetic field of the magnet has direct harm to the human body, so there is no need to worry too much about the magnet magnetic field.

2. Whether the magnetic field is harmful to human body depends on the strength of the magnetic field. Generally speaking, the magnet below 3000 Gauss (magnetic field unit) is not harmful to human body, while the magnet with more than 3000 magnetic field strength is harmful to human body. Some people are afraid that magnetic fields affect the body, but according to tests, magnetic fields are only five times as bad as television.

3. Magnet direct harm to human body: although the magnetic field of the magnet is not harmful to human body, but direct contact with the magnet itself may have the following direct harm. 1 magnet direct suction may cause clamp injury, which in particular ndfeb strong magnet and large magnet on the human body of the injury is greater. 2 magnet from the mouth into the body of the injury is more serious, may hurt life, because the magnet itself with magnetic, in the body of the mutual suction will cause intestinal perforation in the body, after causing massive bleeding, the situation will endanger life, please be careful magnet directly to children play.
