Question 2 (C4, CO2, PO1) An infinite length of wire copper of 5 A is buried underground in the ay direction is parallel to the y axis at x = 2 m, 2=-2 m as shown in figure below. An engineer from electrical utility company needs to measure the magnetic field without screening. The engineer uses a magnetic field meter for measurement. What do you expect about the reading of measurement (in magnitude)? What about if current 5 A flow in the -a, direction is parallel to the y axis? (5 Marks/ Markah) 5.0 A-
