• 12:54, 20 April 2022 Physdemo talk contribs created page Speaker as a Microphone (Created page with "{{NewDemo|subject=Electricity and Magnetism|topic=Inductance|file1=speaker microphone.jpg}} Show how a speaker can be used as a microphone by connecting it to the oscilloscope! As shown in the photo, connect the two wires from a speaker to the CH. 1 input on the oscilloscope using a BNC cable. By tapping the speaker with your finger, you can see waveforms similar to the one in the photo. You can also whistle, yell, or sing into the speaker to show the waveform that your...")
• 12:53, 20 April 2022 Physdemo talk contribs created page Metal Detector (Created page with "{{NewDemo|subject=Electricity and Magnetism|topic=Inductance|file1=MetalDetector.GIF}} The metal detector consists of two perpendicular coils; one hooked up to a signal generator and one to an oscilloscope. A sinusoidally varying current is sent through one coil, producing a changing magnetic field. You can adjust the frequency for resonance ( made by the inherent L and C values of the coil 7130hz for this set-up) for maximum signal transfer. The coils are then adjusted...")
• 12:52, 20 April 2022 Physdemo talk contribs created page Transformers--Frequency Dependent (Created page with "{{NewDemo|subject=Electricity and Magnetism|topic=Inductance|file1=Transformers - Freq Dependent.gif}} A step up transformer is built as shown. With the function generator putting out a 60 Hz sine wave to simulate commercial power the light bulb lights up easily. As the frequency is reduced the brightness of the bulb also reduces until is eventually goes out altogether. A two channel oscilloscope can also be used to track the relationship between the input and output wa...")
• 12:52, 20 April 2022 Physdemo talk contribs created page Lenz's Law Tubes (Created page with "{{NewDemo|subject=Electricity and Magnetism|topic=Inductance|file1=Lenz's Law Tubes.gif}} An aluminum tube with a matching set of cylinders to drop into it. One of these has a magnet within it and takes a very long time to fall through the tube as magnetic fields created within the tube opposes it's motion.

• 12:51, 20 April 2022 Physdemo talk contribs created page Eddy Current Plates (Created page with "{{NewDemo|subject=Electricity and Magnetism|topic=Inductance|file1=Eddy Current Plates.gif}} A copper plate is mounted in such a way that it can swing freely in a plane parallel to the plate. When a magnet is placed in such a way that this plane passes between its poles, eddy currents will be induced in the plate as it passes between the magnetic poles. The result is magnetic braking -- a force arises that opposes the motion of the plate -- and the plate that would othe...")
• 12:48, 20 April 2022 Physdemo talk contribs created page Back EMF (Created page with "{{NewDemo|subject=Electricity and Magnetism|topic=Inductance|file1=Backemf.gif}} A current is run through a coil, which in turn is hooked up to an oscilloscope. A 330 ohm resistor is placed between the positive and negative terminals of the coil. With the oscilloscope in storage mode, a sharp negative peak can be seen to coincide with a spark when one of the banana plugs is pulled from the power supply.

• 12:48, 20 April 2022 Physdemo talk contribs created page Transformers (Created page with "{{NewDemo|subject=Electricity and Magnetism|topic=Inductance|file1=Transformers.gif}} Demonstration transformers made by coupling coils of various turns together with laminated iron bars. Step down or step up transformers can be put together. Meters connected to the primary and secondary measure the voltage. Ratios of voltages are compared to the turns ratio. Results are close. Hysteresis and eddy current losses can be discussed. '''Location: ''' * Coils: Shelf J-3 * T...")

Currents are induced by moving a bar magnet in and out or through the coil. Also available to show this concept is a smaller coil connected to some LEDs. Move the magnet through the coil quickly to make the LEDs light up. '''Location: ''' * Coil Shelf J-3 * Bar Magnet: DR 71 * Galvanometer: DR 83 * Small coil &...")
• 12:46, 20 April 2022 Physdemo talk contribs created page Jumping Rings (Created page with "{{NewDemo|subject=Electricity and Magnetism|topic=Inductance|file1=Jumping Rings.gif}} An AC solenoid with a moveable iron core. Turn the current on with the ring around the core to send it flying. There are heavy and light rings available and one which is cut to show the importance of the induced current in the ring. There is also a small coil with a light bulb to show the presence of this current. '''Location: ''' * Solenoid: Shelf J-3 * Accessories: Drawer 74")
