The class is about Electricity and Magnetism. The website wants exactly the perfect answer and in the same metric system units that are stated on the calculators that are on the picture for the question, if not, it'll mark it wrong.

Set 14 Problem 5 Incomplete Cancellation of Magnetic Field Along pair of wires serves to conduct I = 29.9 A of dc current to and from an instrument. If the wires are of negligible diameter but are d = 3.16 mm apart. what is the magnitude IBI of the magnetic eld a distance L = 9.3 cm from their midpoint. in their plane? What is the ratio IBI/IBE'mhl, where IBml = 50 x 10'5 is the magnetic eld at the Earth. Ratia LEI/133ml =
