... By RHR-2, we see that when the current points up, the mag. field points into the screen, and when the current points down, the mag. field points out of the screen. Thus, I have a changing magnetic field and a changing electric field which are oriented at right angles to each other! The electric fiel ...

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.
