"Hidden" Momentum in a Current Loop
... We consider that these momenta (and energies) are “renormalized” into the “mechanical” momenta (and energies) of the charge and dipole. In addition, there is a nonzero interaction field momentum in the initial state, which is well approximated for low velocities by eq. (10), PEM,int ≈ Eq × m/c. And ...

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.
