Could magnets or a magnetic wrap like material be used to shield sensitive electronic components (or any vulnerable part) of a spacecraft from cosmic rays? The earth's magnetic field has a strength of .3 gauss whilst an N42 neodymium magnet has a strength of 13,200 gauss. The earth produces its own magnetic field which protects us and our technology from cosmic rays, since using dense materials like tungsten or platinum for shielding would hinder a spacecraft in terms of weight (also cost, but predominantly weight) could magnets be placed near the parts of a spacecraft where cosmic rays would affect them so that they simply deflect? I don't know if it's a matter of the size of the magnets that depend on how large the magnetic field is, so perhaps simply placing them where it's needed would be of interest. Maybe even a combination of magnets and insulating materials. Your answer is appreciated.
