1. The problem statement, all variables and given/known data I really think my answer is correct - could someone verify this or let me know where I went wrong? This is problem submitted online, the "correct" answer looks like my teacher accidentally hit the button 3 twice. PROBLEM: The toriod in example 5-1 from the textbook has an inner diameter of 3.1 cm and an outer diameter of 4 cm. 8 amps are flowing through 41 turns on the toroid. What is the field intensity very close to the inside diameter (A/m)? See attachment for figure. 2. Relevant equations Rm = 0.5*(Di+Do)/2 H = Ni/L L = 2*PI*Rm Simply find H. 3. The attempt at a solution I plugged in the numbers many times and keep getting 367.62. My teacher got 3367.92. Looks like the 3 was clicked twice? Any help appreciated.
