1. The main function of the magnetic backboard is to facilitate the user to use and protect the mobile phone, instead of producing magnetism to directly act on the human body.
2. The magnetic material used in the magnetic absorption backboard is specially designed for consumer electronic products such as mobile phone cases, and its magnetism is relatively weak. This kind of magnetic material does not have obvious influence on human magnetic field like strong magnetism.
3. Modern medical devices have adopted non-magnetic materials, which means that these medical devices will not be affected by the magnetic attraction of mobile phones.
In our daily life, we are exposed to a lot of electromagnetic fields, such as TV, computer and microwave oven. Compared with these devices, the magnetic material in the mobile phone case is insignificant, so it will not have a negative impact on the human body.
