Student Name: a) Two magnetic mediums are separated by the parabola y² = x − 3 associated medium 1 which has permeability 3.33µ0. The total magnetic field in medium 1 is

given as H₁ = The surface current at the boundary Kf find the magnetic field in medium 2. 3x²z Y = Student ID: Tây +4ryzây 3.x. If the permeability of medium 2 as 6.66µ0, b) A Toroid with an air gap as shown in Figure 1 below, has a square cross section. If I₁ = 200 mA, N = 750, po = 10 cm, a = 5mm and the length of the air gap L₁ Find: (a) The total magnetic flux & when I2 = 0 and the relative permeability of the toroid μ = 300 (b) The total magnetic flux & when I₂ = 2 mA and the permeability of the Toroid is infinite (μ = ∞) (bonus)
