Electromagnetic Field Theory
Magnetic circuit with cross sectional area of 20 cm2 is to be operated at 50 Hz from 120 Vrms supply. The number of turns required to active a peak magnetic flux density of 1.8 T in the core flux is
An electric flux line is an imaginary path or a line drawn in such a way, that its direction at any point is the direction of electric field at that point.
Gauss’s law states that total electric flux through any surface is equal to the total charge enclosed by surface.
For a uniform long charged line with l1 c/m the electric field intensity E is given as E = ρL/(π ε0.r).
