Transition notes:

1. The large lab magnet, the cylindrical magnets, the banana plug leads, alligator adapters, and the 45 cm rod on the “A” base stay out from Lab 8 for Lab 9: Magnetism 2. The power ampilfier needs to be switched from analog B to analog C.

Equipment List:

1. Pasco 750 Lab interface with the following sensors:
• Pasco Voltage Probe (Analog A) (C25.H)
• Pasco Power Amplifier (Analog C)
• RMS (C3.1) on 45 cm horizontal rod (A1) attached to 90 degree clamp (C10.3), on a 45 cm rod  (A1) in an “A” base (C20.1) (yellow DG1, black DG2) for use with the 200 Turn Induction Wand (Pasco EM-8099). See the setup notes for instructions on how to set this up.
2. Galvanometer (C29.4)
3. Banana plug cables
   • 3-red (C21.H)
   • 3-black (C22.H)
   • Four red and four black alligator clip adapters (B2.3)
4. Set of 2-cylindrical permanent magnets (C28.2)
5. Helmholtz coil base (Pasco EM6715) (C29.1)
6. 200 Turn Helmholts Field Coil ( Pasco EM6711) mounted on a Helmholtz base. (C29.3)
7. 200 Turn Induction Wand ( Pasco EM-8099) (C29.3)
8. 400 Turn Detector Coil ( Pasco EM-6712) (C29.3)
9. 2000 Turn Detector Coil ( Pasco EM-6713) (C29.2)
10. Variable Gap Magnet ( Pasco EM-8641) (C28.3)
11. Small metric ruler (C10.2)

General Lab use:

1. Lenz’s law demonstrator (1-2 per quadrant) placed on the TA table and a set up cart. The Lenz's law demonstrator consists of a long tube (B1) and two cylinders (C29.1), one that is magnetic and one that is not. Include a stopwatch (C3.4) with each demonstrator.

Notes and tests:

1. Load the test file “2306_Lab9_Magnetism2_ test1.ds”. Drop a magnet through a coil wand attached to the voltage probe, and check that the induced voltage is registered. Move the rotary motion sensor and make sure it registers correctly.
2. Hook the voltage probe to an induction wand and the power amp to the large coil as in the picture. Load the test file “2306_Lab9_Magnetism2_ test2.ds” Test that the power amp is putting out a current and when you put the wand in the middle of the coil and move it around you get changes in the induced voltage.
