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 = ?
B = mu0/2pi * NI/r[/B]
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?
