Asked by Lanise
Two long, parallel wires separated by 50 cm each carry currents of 3.0 A in a horizontal direction.
Find the magnetic field midway between the wires if the currents are in the same direction.
B= T
Find if they are in opposite directions.
B= T

Have you heard of Ampere's law? That is what you need to use.

The answer should be obvious for the same-direction case. For the opposite-direction case, double the field due to a single wire.
