🤓 Based on our data, we think this question is relevant for Professor Heidarian's class at UMD.

Solution: A very long straight current-carrying wire produces a magnetic field of 20 mT at a distance d from the wire. To measure a field of 5 mT due to this wire, you would have to go to distance of A) 2dB) 8dC) d√2D) 4dE) 16d
