A toroid has 390 turns of wire and carries a current of 18 A. Its inner and outer radii are 7.4 and 11.2 cm. Find the magnetic field at r = 8, 8.8, and 9.4 cm. Hint a. Choose the description that most correctly describes the direction of the magnetic field at these locations. The magnetic field points in radial direction. O The magnetic field is perpendicular to the toroid plane. The magnetic field points in tangential direction. The magnetic field points in the z direction. b. Magnetic field at r = 8 cm is 3.51 c. Magnetic field at r = 8.8 cm is 3.19 d. Magnetic field at r = 9.4 cm is 3 ☑ = 3.51 mT. = 3.19 mT. × = 3 mT.
