... Negative charge, very small mass, forms cathode rays, can be bent by magnetic or electric fields. b. Particle nature. This is because the rays are considered to be streams of electron particles that charge up objects when they hit them. c. Wave: Could move through thin foil, wavelength decreases as ...

... indeed behaves like a DC field. The solution to (2) has to be found using numerical methods if the particular device is complex and therefore, the electric field highly inhomogeneous. However, if there are zones with a high and homogeneous electric field, an analytical approach to (2) can be used [2 ...

... THE MAGNETIC VECTOR POTENTIAL A ( r ) We saw in electrostatics that ∇ × E = 0 {always} (due to intrinsic / microscopic nature of the electrostatic field) permitted us to introduce a scalar potential V ( r ) such that: E ( r ) ≡ −∇V ( r ) {n.b. V ( r ) is uniquely defined, up to an (arbitrary) consta ...

... Faraday's law is not an explanation of induction but merely a description of of what induction is. It is one of the four "Maxwell's equations of electromagnetism" all of which are statements of experimental results. We have already encountered Gauss' law for the electric field, and Ampere's law (in ...

... To faithfully simulate ITER and other modern fusion devices, one must resolve electron and ion fluctuation scales in a five-dimensional phase space and time. Simultaneously, one must account for the interaction of this turbulence with the slow evolution of the large-scale plasma profiles. Because of ...

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.
