Suppose you wish to produce a 2-T magnetic field in a toroid with an iron core for which magnetic susceptibility is x = 6 x 10°. The toroid has a mean radius of 11 cm and is wound with 350 turns. Hint a. What current is required to produce this magnetic field in the iron core? Current of A is needed. b. For comparison, what current is required to produce the same magnetic field in an air-filled toroid of same geometry? Current of A is needed for toroid with no iron core. While it is not always practical to have region of magnetic field filled with ferromagnetic materials, this dramatic increase in strength of magnetic field produced is useful in some applications you will see in upcoming chapters.
