Magnetic Flux

Magnetic Flux problem 2

The table below shows the relative permeability values of different materials. A cylindrical material, with the listed permeability, is placed in a coil 30 cm long and is surrounded by 200 turns of wire through which a current of 3 A flows.

  • Identify which of the following materials is a ferromagnet, paramagnet or diamagnet.

  • What is the magnetic flux density inside an individual cylinder made of ferromagnetic material when it is in the coil?
