  1. Measuring Magnetic Fields] The horizontal component of the Earth’s magnetic field is 2 x 10-5 Tesla. Suppose you bring a bar magnet such that it is 3 cm from a magnetic compass. The bar magnet makes the compass deflect 15.6 degrees. What is the strength of the magnetic field due to the bar magnet at that location?  Suppose this bar magnet is a magnetic dipole. What is the value of the magnetic dipole moment? Remember that

At the equator, the earth’s field is essentially horizontal; near the north pole, it is nearly vertical. In between, the angle varies. As you move farther north, the dip angle, the angle of the earth’s field below horizontal, steadily increases. Green turtles seem to use this dip angle to determine their latitude. Suppose you are a researcher wanting to test this idea. You have gathered green turtle hatchlings from a beach where the magnetic field strength is 50 μTμT and...

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...
