What would it be like if humans could sense the magnetic field?

Let me put it this way: if you go to the hospital, it is full of sick magnetic fields, and you will feel very uncomfortable. If you go to quiet places and mountain tops, you will feel as relaxed as a gust of wind. If someone's feng shui is not good, you can sense which direction the magnetic field is good or bad when you stand in his house, or if a person is unwell, you can know that his part is uncomfortable when you sweep his body with your hand, just like a scanner. If you can't control it, you will absorb the magnetic field. Don't go to places where you are in a bad mood, and don't go to the hospital, otherwise it will be very uncomfortable. Obviously, for example, if you are in a room, one hand is raised to feel the sky, and the other hand should feel it in the dark underground. After a while, the temperature of your hands will be different. One hand will be cold, but there are actually many, many, many. I can't say it one by one. When you use it correctly, life is always full of fun. If it doesn't work well, it's very helpless. The magnetic field in a bad mood will be absorbed by you every day.
