- I I,- The picture shows two perpendicular wires where I1 is 14.6 amps, and I2 is 21.9 amps. The location A is in the plane of the two wires and is 25.0 mm from the x-axis and 15.9 mm from the y-axis. Given the direction of current in each wire, what is the B-field at the location A in micro teslas? (If the B-field points toward you, make it positive; if it points away from you, make it negative. Give answer as an integer with correct sign. Do not enter unit.)This is not an essay question, im trying to figure out how to solve for the solutions.A 0.68 T magnetic field is applied to a paramagnetic gas whose atoms have an intrinsic magnetic dipole moment of 1.3 x 1024 J/T.
