~ 3 ~ I. Introduction : In this experiment we will measure the magnetic field of Earth. We will measure the horizontal and vertical components of the magnetic field with a compass and dip meter before charging our tangent galvanometer and allowing current to change the position of our compass. By the end of this experiment we will measure the magnetic charge at the center of the galvanometer as well as the magnetic field of Earth. Experimental Set-up : We will be using a Tangent galvanometer made of 15 loops of wire, a compass, dip needle, power supply, and connecting wires. *note: An ammeter should have been used instead of the power supply display. Experimental Procedure : 1. First we measured the radius of the coils and counted exactly how many there were before recording it into our data table. Then we placed the compass on the center of the coil and aligned the coils to be parallel with geographical North and South. At this time,
