Magnetic Fields Hall Effect Sensor and Tangent Galvanometer By: Rory McPherson TA Jie Zhang Lab Partners: Andrew Wallach, Michael Russell Abstract: Surrounding a magnet there is a magnetic field. The magnetic field is analogous to the electric field that exists in the space around electric charges. Like the electric field, the magnetic field has both a magnitude and a direction. The direction of the magnetic field at any point in space is the direction indicated by the north pole of a small compass needle placed at that point.

Introduction: Since electric current is a flow of charge, the behavior of a compass needle in the presence of current carrying elements indicates that moving charges produce a magnetic field. For a loop of wire consisting of N turns wound close together to form a flat coil with a single radius R, the magnetic field resembles the pattern of a short bar magnet, and at the center of the coil its magnitude is: Where μ 0 is the permeability of free space (4 π 10
