Magnetic fields affect moving charged particles and other magnetic fields.

They do not affect moving uncharged particles, motionless charged particles, or electromagnetic waves. For example, light is an electromagnetic wave, and it is unaffected by magnetic fields, even those much stronger than the Earth's magnetic field, such as just about any bar magnet, speaker magnet, etc.
