Electric and magnetic fields - The Physics of Bruce Harvey
... The primary purpose in nature of magnetic fields is to surround moving elementary charged particles and contain their potential energy. When elementary charged particles move in a co-ordinated way, they generate an extended magnetic field. This is a secondary function of nature. If we are to underst ...

Electromagnetism - Lecture 9 Dielectric Materials
... Some molecules have an intrinsic dipole moment p =ea, where |a| ≈ 10−10 is the molecular size. These polar dielectrics have large dielectric constants. An example is water with r = 81 at room temperature In the absence of an external field E the molecular dipoles are randomly oriented and P = 0 In ...

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.
