a filamentary conductor on the z axis carries a current of 10(A)in the a_z direction and a coaxial conducting shell at r=8mmcarries a total current of 5(A) in the z a_z direction. the region3mm<r<5mm is a solid conducting material carrying a uniformlydistributed total current of 5(A) in the a_z direction.find themgnetic flux H in the region 0<r<3, 3<r<5, 5<r<8,8<r<10. and the total magnetic flux
