... 3. In order to calculate directly the magnetic field we first have to understand that we have an infinite cylinder which is uniformly charged and the charge is moving. So we can analog this to an infinite wire, with a radius R, and a cavity parallel to it’s axis at a distance a and with a radius b, ...

RF-DNA: Radio-Frequency Certificates of Authenticity
... We stress that reader’s measurements represent EM effects that occur in the near-field of the transmitter, the COA instance, and the receiver; distances between any two objects are proportional to the wavelengths of interest. We observe EM effects in the near-field for several reasons: • It is diff ...

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.
