... minimized by using thin laminated core. 2. Hysteresis loss due to alternately passing a current in the coil to magnetize and demagnetize the iron core. This can be reduced by using a special alloy of iron core with silicon. So material with less iron loss and less hysteresis loss is used for making ...

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.
