In magnetic laboratory of Govt. College University, 37.200 tesla value of magnetic field is achieved. For achieve such magnetic field, (i). Calculate the value of required electric current at 2 ×10-2 m from the long wir (ii). Compute the value of required electric current at the center of coil made up of 100 turns with radius 42 ×10-2 m (iii). Determine the value of required electric current near the center of solenoid made up 4× 104 turns with radius 2.4×10-2 m and its length 32×10-2 m.
