Experiment 10A: To study the Magnetic Fields-By using a Magnetic Field Sensor to discover the characteristics of fields around magnetized materials. Equipment: Magnetic Field Sensor CI-6520A 750 Interface Various Magnets ( Bar) Iron Bar (Mass from Dynamics Carts) Experimental Setup for the Science Workshop Interface using Data Studio: 1. Connect the Science Workshop Interface to the computer. 2. Plug the Magnetic Field Sensor into analog channel A. 3. Set the switch on the sensor to axial (see photo below).Select Suitable Range 4. Place a small piece of tape on the desktop and set the Magnetic Field Sensor on the tape (see photo below). You are now ready to begin collecting data.

Data Collection Procedure: 1. Hold a bar magnet about 20 cm from the end of the Magnetic Field Sensor. 2. Click the Start button, then slowly move the magnet toward the sensor until the magnet just touches the snout of the sensor. 3. Hold the magnet next to the snout for a second, then slowly move the magnet back to a position about 20 cm from the sensor. Data collection will automatically stop after 10 seconds. 4. Flip the magnet around 180 degrees and repeat steps 1-3 for the same magnet. 5. Repeat steps 1-4 for a bar magnet. 6. Move all magnets at least 1 meter away from the sensor and place the end of an iron bar up against the Magnetic Field Sensor. 7. Click Start, then pull the length of the bar along the sensor (see photo below). Data collection will automatically stop in 10 seconds.

8. Next, place the bar magnet near one side of the iron bar for 10 seconds. Do not allow the magnet to physically touch the iron bar. 9. Move the magnet at least 1 meter away from the sensor. 10.Again, place the end of the iron bar up against the Magnetic Field Sensor. 11.Click Start, then pull the length of the bar along the sensor as you did in step 7. Data collection will automatically stop after 10 seconds. 12.Repeat steps 8-11, except actually place the bar magnet on the side of the iron bar for 10 seconds before measuring its magnetic field

Conclusions/Questions: 1.What does the shape of the magnetic field graph tell you about the relationship between the magnetic field and distance? 2.How does the slope of the magnetic field graph change as you move the sensor relative to the magnet?
