The Earth's magnetic field acts within a volume with a dimension of, say, $10^6$ m (comparable to the Earth's radius). Therefore, to deflect charged particles of the same momentum you need a "simple magnet" with a magnetic field that is $10^6$ stronger than the Earth's magnetic field, i.e., tens and hundreds of Tesla. This is impracticable for protection of electronics (as far as I know, the field of the strongest laboratory DC magnet is 45 Tesla). | |
