This is due to the direction of the magnetic field

This preview shows page 3 - 5 out of 8 pages.

This is due to the direction of the magnetic field being directed straight down the axis of the longsolenoid. A long solenoid is considered long if the actual length of the coil is significantly larger than the diameter of the coil. Since ndepends on length per unit length, Equation 2 will fail once the ends of the solenoid are in contact with the magnetic field. The magnetic field strength will then be forced to decrease. For a short solenoid, neither Equation1 nor Equation 2 will be effective because it is too long for Equation 1 to work. It is also substantially small for Equation 2 to be used, since it doesn’t pass the given restrictions above. Equipment: AC/DC Electronics Laboratory Rotary Motion Sensor 2-Axis Magnetic Field Sensor Short Patch Cords (set of 8) Large Rod Base 90 cm Rod, Stainless Steel Mass and hanger set Black thread 850 Universal Interface Pasco Capstone Experimental Procedure: Place the Magnetic Field Sensor probe into the coil so that the sensor is at the center. The vertical position of the sensor is displayed on the sensor’s body with a white dot. Make sure to tare the sensor at zero. Click open Data Summary in the Capstone application. Under the Rotary Motion Sensor properties tab and click “Zero Sensor Now”. After clicking ok, open the signal generator. Next, insert the magnetic sensor probe through the solenoid. Click Record and remove the probe slowly about 10 cm away from the solenoid. Try and remove it at the center as close as possible. Make sure to click stop. Make sure the curve is symmetric about position=0. Re-label
