They did on CRT tubes. When I worked at Apple we had a big enclosure made of coils with a wooden desk in the middle. There was a map on the wall of the earth and you could pick any location, read the parameters from the chart and type them into a control panel to filter the Earth's magnetic field in that location inside the chamber.

When we still made CRT monitors they were calibrated for certain geographic regions and we tested that calibration in this machine. There was always a push to make fewer monitor calibrations but the best we ever got to was northern and southern hemisphere models
