The intensity of the toroidal magnetic field in a tokamak is proportional to the inverse of major radius (B~1/R). In ITER, the toroial magnetic field is at the magnetic axis (R = Ro ) is 5.3 Tesla. The total plasma current of ITER is I, 15MA. Assume the circular plasma cross section, and the major radius Ro = 6.2m and the minor radius a = 2.0m %3D (a) Find the poloidal magnetic field Be at the last closed flux surface (r = a). Use the Ampere's law, giving Be 2na = µol, where uo = 4n x 10-7 [Hm-] (b) Find the ratio of the toroidal magnetic field to the poloidal magnetic field at the outer-midplane (R = Ro + a) and the inner-midplane (R = Ro - a) The intensity of the toroidal magnetic field in a tokamak is proportional to the inverse of major radius (B~1/R).
