RUNNING HEAD: THE MAGNETIC FIELD IN A COIL EXPERIMENT NO. 4 Module Title: Engineering Physics II In partial submission for the Bachelors of Engineering ( Electrical Engineering) To University of Technology Jamaica Mr. Mangaroo Date: February 1, 2017 By David Godson | | 1605057 Julius Reid | | Shemario Moriah | | 1600517 EXPERIMENT NO. : 4 TITLE: The Magnetic Field in a Coil
THE MAGNETIC FIELD IIN A COIL AIM: To examine how magnetic field is related to current through the coil. THEORY: When an electric current flows through a wire, a magnetic field is produced around the wire. The magnitude and direction of the field depend on the shape of the wire and the direction and magnitude of the current through the wire. If the wire is wrapped into a loop, the field near the center of the loop is perpendicular to the plane of the loop. When the wire is looped a number of times to form a coil, the magnetic field at the center increases. In this lab, you will examine how the magnetic field is related to both the number of turns in a coil and the current through the coil. A Magnetic Field Sensor will be used to detect the field at the center of the coil. A complication that must be considered is that the sensor will also detect the Earth’s field and any local fields due to electric currents or some metals near the sensor. To determine the current through the coil you will measure the voltage across a 1 ohm resistor in series with the coil. Using Ohm’s law, I = V / R , we find, for example, that a voltage of 2 V across the resistor will correspond to a current of 2 A through the resistor. OBJECTIVES: Use a Magnetic Field Sensor to measure the field at the center of a coil. Determine the relationship between magnetic field and the number of turns in a coil.
THE MAGNETIC FIELD IIN A COIL Determine the relationship between magnetic field and the current in a coil.
