Question

Q5 Two long parallel wires carry currents of 20A and 5A in opposite directions. The wires are separated by 0.2 m. What is the magnitude of the magnetic field midway between the two wires? (take μ,-4x × 10-7 T m/A) a) 0 b) 1.0×10-5 T c) 2.0 x 10 T d) 3.0 x 10 T e) 4.0 x 10S T f) 5.0×10-5T Q6 A coil of wire has an ammeter attached to it.
