No Chatgpt or ai please 3. Toroida)A toroid is formed by winding a wire which carries current I with N turns. Thetoroid has a mean radius R, and a cross-section radius r. which is smaller than R.Using Ampere's law, derive an expression for B inside the toroid as the funcitonof radial distance r which is the distance from the center of the toroid. Again,draw a figure with an amperian loop, direction of the path, and the direction ofthe magnetic field.ToroidR mean radiusr = cross-section radiusrcRN = 2000, I = 2A, R = 20 cm, rc=6 cm for part b) and c)= 5500. Find theb) Inside the toroid is filled with annealed iron with Xmmagnitude of the magnetization at r = R.c) Find the magnitude of the total magnetic field at r = R +/2 of the annealediron filled toroid.
