)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. We generally use a compass when its face is oriented parallel to the ground, consequently only picking up the horizontal component of the earth’s magnetic field. Say you were on planet X and feeling a magnetic field of 30.0μT horizontal to the surface of the planet. If you passed 480mA of current through on a current loop of diameter 20.0cm, how would you orient the loop so that your compass needle rotates 45 degrees. (Your compass face is level with the surface of the planet, and at the center of the loop.) (Please type answer no write by hend)
