Inductors - Technical MCQs

Q1:

What is magnetic flux?

A the number of lines of force in webers

B the number of lines of force in maxwells

C the number of lines of force in teslas

D the number of lines of force in flux density

ANS:A - the number of lines of force in webers

Magnetic flux (most often denoted as m), is the amount of magnetic field (also called "magnetic flux density") passing through a surface (such as a conducting coil). The SI unit of magnetic flux is the weber (Wb) (in derived units: volt-seconds). The CGS unit is the maxwell.
