1. The problem statement, all variables and given/known data 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 B inside the toroid. A) Bmaximum = ? B) Bminimum = ? 2. Relevant equations B = mu0/2pi * NI/r 3. The attempt at a solution 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?
