The fortune teller said that my magnetic field is not good.

The fortune teller is talking nonsense. Fortune-telling is an ancient knowledge in China. I can't say how accurate it is, but it's definitely not related to the magnetic field. China had the concept of magnetism in ancient times, but absolutely no concept of field. The concept of magnetic field is completely western, and the magnetic field mentioned by fortune tellers is pure nonsense. Fortune-telling You can say that you are unlucky, but you must never say that your magnetic field is bad.
