Magnetic Field Lab In this lab will be using a Hall Probe to directly measure the strength of the magnetic field produced by a current flowing in a solenoid , a toroid, as well as a straight wire. Procedure 1. Launch LoggerPro 2. Open the file the "Hall Probe" 3. Follow the directions to calibrate the probe The Solenoid (Use I=2.5A) 4. Measure and plot the magnetic field at the middle of the length of the solenoid and the center of the cross-section. Move radially outward in steps of 0.5cm out to a radial distance of 10.0cm. Also move in the opposite direction (call it negative) from the center out to a negative 10.0cm (-10.0cm) in steps of -0.5cm. Also plot the theoretical value on the same graph. 5. number of turns of the solenoid (N). Go from N=18 up to N=45 in steps of 3. You don't have to also measure radially like you did in step 4. Also plot the theoretical values on the same plot. 6. Measure and plot the magnetic field at the center of the solenoid as a function of the current, I. Let I=0 to I=2.7A in steps of 0.3A. Also plot the theoretical
