[QUOTE="Angie K., post: 5106932, member: 550788"] [h2]Homework Statement [/h2] A toroid has a 49.4-cm inner diameter and a 57.4-cm outer diameter. It carries a 23 A current in its 500 coils. Determine the range of values for [I]B[/I] inside the toroid. A) Bmaximum = ? B) Bminimum = ? [h2]Homework Equations[/h2] B = mu0/2pi * NI/r[/B] [h2]The Attempt at a Solution[/h2] I tried plugging in the values from the problem but I am not sure where I am going wrong. B minimum = Mu0 * 500 * 23 / 2 pi * (.494/2) B maximum = Mu0 * 500 * 23 / 2 pi * (.572/2) Am I doing something wrong with the radius? Is the B minimum not thre inner r and the maximum the outer r?
