[[bsc:emt:nasir:magnetic_field|Magnetic Field Effects]]\\
A magnetic field may be represented by a mathematical description of the magnetic influence of electric currents and magnetic materials. The magnetic field at any given point is specified by both a direction and a magnitude (or strength); as such it is a vector field...[[bsc:emt:nasir:magnetic_field|read more and download]]

[[bsc:emt:nasir:inductance|Inductance]]\\
In electromagnetism and electronics, inductance is that property of a circuit by which a change in current in the circuit "induces" a voltage (electromotive force) in both the circuit itself (self-inductance) and any nearby circuits (mutual inductance)...[[bsc:emt:nasir:inductance|read more and download]]
