A long current carrying wire is formed into a square loop with sides of 10 cm. A compass placed below one side of the loop shows a deflection to the west of 35 degrees. The distance between the wire and compass needle is about 3 mm. What is the magnitude of the current in the wire? The magnetic field of the earth is about 2e-5 T. (This should be on your notes page. This will not be given on the test.) X A N The correct answer is: 0.21 A long current carrying wire is formed into a square loop with sides of 10 cm. A compass placed below one side of the loop shows a deflection to the west of 35 degrees. The distance between the wire and compass needle is about 3 mm. What direction is the current in the loop? The magnetic field of the earth is about 2e-5 T. Select one: O a. clockwise O b. counterclockwise O c. Can't tell from information given. Your answer is incorrect. The correct answer is: counterclockwise This same scenario is used in a few different questions on this test. You can get one question wrong and still get others correct. Imagine you find the current in the wire to be 0.55 A. A long current carrying wire is formed into a square loop with sides of 10 cm. A compass placed below one side of the loop shows a deflection to the west of some number of degrees. The distance between the wire and compass needle is about 3 mm. What is the magnitude of the magnetic field in the center of the square due only to the loop of wire? X T N The correct answer is: 6.22253E-6
