Magnetic Field of a Solenoid Shannon Berg October 28, 2010 Physics 255b Section 4 Object The purpose of this experiment is to compare theoretical values and experimental values for magnetic field. In order to make the magnetic field value comparison, the axial component of the magnetic field inside a solenoid will be measured and the theoretical value for the magnetic field will be calculated. Apparatus 1) PASPORT Voltage-Current Sensor 2) PASPORT Magnetic Field Sensor 3) 2 USB Links 4) Primary and Secondary Coil 5) Meter Stick 6) Power supply, 18 V DC, 5 A Procedure 1) Measure the length of the outer solenoid coil on the Primary/Secondary Coil set. 2) Connect the DC Power Supply output to solenoid input jack using patch cords. 3) Attach the current portion of the Voltage-Current Sensor to the solenoid using patch cords. 4) Turn on the DC Power Supply to 10 V.

Unformatted text preview: 5) Place Magnetic Field Sensor in the center of the solenoid. 6) Click Start, record current and magnetic field strength, and click stop. 7) Slowly insert the Magnetic Field Sensor into the solenoid while plotting the field strength. 8) Click Start with the Magnetic Field Sensor just on the outside of the solenoid. 9) Click Keep and the first value for Magnetic Field will appear in the first cell. 10) Move Magnetic Field Sensor 1 cm at a time and click Keep each centimeter. 11) Collect 7 values and click Stop and then click Scale to Fit. Theory Statement By experimentally finding the current (I) through a solenoid with a given number of turns (N), length (L), and using the permeability of free space ( ), the magnetic field (B) can be determined using the following equation. = B 0NIL 1 2...
