... Furthermore we also assumed that the current has the same magnitude along the wire or that its divergence is equal to zero. This condition will guarantee that the charge density is constant independent of the time, so no changing electric fields either. The magnetic field around a current distributi ...
Time in physics
Time in physics is defined by its measurement: time is what a clock reads. In classical, non-relativistic physics it is a scalar quantity and, like length, mass, and charge, is usually described as a fundamental quantity. Time can be combined mathematically with other physical quantities to derive other concepts such as motion, kinetic energy and time-dependent fields. Timekeeping is a complex of technological and scientific issues, and part of the foundation of recordkeeping.
