magnetic field from current in a long straight wirevan Wijk, Kasper
A long straight wire carrying a current is the simplest example of a moving charge that generates a magnetic field. The force a charge feels when moving through a magnetic field depends on the right-hand rule. The direction of the magnetic field due to moving charges also depends on the ...
Radiation field Correct Answer B. Magnetic field ExplanationMagnetic field is the area around a magnet. The magnetic field is the region around a magnet where the magnetic forces are observable. It is defined by the presence of magnetic force on moving charges, which are experienced as attrac...
