Descriptive ethics will hence try to oversee whether ethics still holds its place. Because descriptive ethics involves empirical investigation, it is a field that is usually investigated by those working in the fields of evolutionary biology, psychology, sociology or anthropology. Information that comes from descriptive ethics is, however, also used in philosophical arguments.
To deactivate an ICD or alter pacemaker function, a magnet has to have a field strength of 10 gauss (a unit of magnetic strength) or greater next to the surface of the device. A magnet in a stereo speaker has a field strength of 100 gauss at the surface - but 0 gauss 6 inches away.
The changing magnetic field induces an alternating voltage in the coil that can be measured. The frequencies and amplitudes of the alternating voltage are related to the wheel speed (Fig. 1) . Passive inductive sensors do not need a separate power supply from the control unit.As the signal range for signal detection is defined by the control unit, the amplitudes must be within a voltage range.he changing magnetic field induces an alternating voltage in the coil that can be measured.
