Is the B Field Constant Inside a Toroid?

Is the B field constant inside a toroid?
Like we would just use amperes law to find.
B(2*pi*r)=(mu_0)NI
But after talking to this kid he said it changes inside. But i thought it was constant.

Where N is the numbers of turns ?
Didn't think the question was hard . Just not sure if s is fixed .

Its ok i figured it out . The field inside the toroid does vary with the radius, stronger on the inside edge and weaker on the outer edge .
