... In a uniform electric field the force on a charged particle is always in one fixed direction, as with gravity near the earth's surface, leading to parabolic trajectories. In a uniform magnetic field the force of a charged particle is always at right angles to the motion, resulting in circular or hel ...

Electromagnetic Waves
... Electromagnetic Waves EM waves can be produced by an antenna, which is just some kind of wire that is connected to an ac source. The ac source produces oscillating + and charges which set up electric field (due to the separation of charge) and a magnetic field (due to the current in the wire). ...

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.
