Rubber soled slippers generating static electricity - Physics Forums
2019年2月2日 · Alternately, you may be able to mix some conductive <something> in with your carpet shampoo to make your carpet more conductive. I'm not sure what that would be, but there should be something out there (I can try searching for it if you want). You can also buy an inexpensive ESD meter to measure the effectiveness of your solutions.
Build a Tall and Stable Popsicle Stick Tower - Physics Forums
2009年9月1日 · Tape the sticks together at the top and attach it to the top level of the tower using masking tape. 8. To ensure maximum stability, reinforce the connections between each level and the base by wrapping masking tape around them. 9.

How Does a Tin Can Phone Transmit Sound? - Physics Forums
2010年7月30日 · In summary, a tin can phone works because the bottom of one can vibrates with the sound waves produced by the speaker's voice, and this vibration travels through the string to the other can, causing the bottom of the second can to vibrate and produce sound waves that can be heard by the listener.
Best way to connect 8 wires together? - Physics Forums
2018年9月25日 · Can I use electrical tape to connect 8 wires together? While electrical tape can be used to connect wires, it is not recommended for connecting 8 wires together. The tape may not provide a secure connection and can loosen over time, potentially causing electrical hazards. It is best to use a wire nut or connector for connecting multiple wires.

Does copper or aluminum sheet block magnetic signal? - Physics …
2012年3月27日 · I have a discussion about shielding of noise generated by appliance and florescent lights. I know both Al and Cu are not magnetic material. BUT all noise are time varying meaning it is EM field. Good conductor block E field as loss is very high. How does that work when only the B field can pass...
