There is a high-voltage line in front of my house. How to break the magnetic field chaos?

Hello, electric current can produce a magnetic field. The greater the current, the stronger the magnetic field. At the same time, there is also a magnetic field on the surface of our earth. We can't remove the geomagnetic field, we just need to cut off the magnetic field generated by the current. Therefore, if the high-voltage line can't be moved, your family will have to move.
