Web16 jul. 2024 · Keays is testing a long-forgotten hypothesis, first proposed in 1882, that as a bird flies through Earth’s magnetic field, tiny electric currents are generated in its ear. This would happen through electromagnetic induction, akin to how a magnet that moves through a coiled wire creates an electric current in the wire. WebKey terms. A field models what an object would experience related to a force at a given point in space. A magnetic field is a field explaining the magnetic influence on an object in space. A electric field is a field defined by the magnitude of the electric force at any given point in space. Current is the rate of charge moving past a region. WebMagnetic Field.
