Student Name: Student ID: a) A Toroid with 350 turns has inner and outer of radii a = 2 m and b = 5 m respectively is carrying a uniform current

of I = 3mA. The permeability between a and b is given as 5.510. (a) Find the Magnetic field and the magnetic flux when p = 3 m. (b) Obtain the bound currents J, and Ki (c) Is the Toroid Paramagnetic or Diamagnetic ? b) Given then magnetic potential A = = 4xyz²â+3zxy²ẩy for the surface S formed by the closed path described by { € [-2,3], y = [-2, 4], z = 2} in the counter-clockwise direction. Obtain the magnetic flux through the surface m.(bonus)
