- Explain that magnetic fields an example of field of force produced
- Magnetic fields are an example of the field of force produced by a force-carrying particle. A magnetic field is a physical field produced by magnets or electric currents.
- The Earth’s magnetic field is used for navigation by some migratory animals, including birds and turtles. For humans and other land-based life forms, it manifests in the aurora borealis, or northern lights (aurora australis, or southern lights, also occur but are not as visible to the naked eye).
- The movement of a charge in an external magnetic field produces a force on it, according to the Lorentz force law. In addition to moving charges produce magnetic fields; static distributions of charges and currents also produce magnetic fields.
- A magnetic field is a physical field produced by magnets. The term “magnetic field” is used for two distinct but closely related fields denoted by the symbols and . An external magnetic field , produced by an electromagnet, will exert a force on other magnets placed in the vicinity of the magnet producing the field; this effect is known as magnetic induction.
- The magnetic field also deflects particles in orbit around the Earth known as the Van Allen radiation belts; were it not for this protection, life as we know it would probably not exist.
