Magnetic Flux We've already seen terms like voltage and current to describe the quantities associated with electricity, however, we need to look at how magnetism is quantified. Magnetic lines of force are also known as magnetic flux. The strength of magnetic flux is measured in webers (abbreviated Wb) named after Wilhelm E. Weber. Older textbooks will use the maxwell (or Mx) instead, named after James Clerk Maxwell. If you have to convert from one to the other, 1 Wb = 10$^{8}$ Mx [Woram, 1989].
