Problem Statement
Consider a toroid which has N = 50 turns. The toroid has an ID = 10cm and OD = 15cm. For a current i = 5A calculate the field intensity H along the mean path length within the toroid. (this problem is similar to Example 5-1 in the text book)
Solution
The magnetic field intensity Hm is constant along the circular contour because of symmetry. The mean path length is The mean path length is
