Magnetic Forces, Materials, and Inductance Q7) Calculate the magnetic flux inside a toroid with 8000 turns by drawing its magnetic circuit if it has a 15 cm radius, a cross-sectional area of 10 cm, and an air gap of 2 mm. Assume the flowing curent is 250 mA. (Use Figure (9.11) in the book for any required information).
