Lab Scenario: You don't have a current meter in your underequipped lab. So you make one out of a compass. The wire you want to measure the current in is aligned with the North South line. You place your compass directly under the wire at a distance of 10cm from the wire. With no current flowing, the compass needle points due north. When you turn on the current, the compass needle points 5 degrees west of north. You now have...
