| What does the insulation have to do with magnetic fields. Removing the insulation from half the coil would create a short cct. |

| It's just a simple motor, like for a school project or a demo, it isn't meant to be a really strong motor. |

| I wonder what would happen without the magnet |
| Nothing. nothing ... ( 2 days ago by wmgarab) |
| Nothing. nothing would happen without the magnet, because there would be no magnetic field to push on the charges flowing around the coil of wire. it would just sit there and heat up conducting the energy until it overheated and either melted, or burned the contacts...or the battery went dead. |
| naisayd: Only the ... ( 1 day ago by Asparition) |
| naisayd: Only the ENDS of the coiled wire insulation get stripped off half way around. If the insulation is stripped all the way around the tips, then the coil would act like a permanent magnet itself and just lock in place (and would actually resist being spun). It spins because it's ONLY behaving like a magnet half the time when it spins back to that point. Nikola Tesla invented electric motors that power full-cycle. Well, okay, microscopic flagella have had living motors long before Tesla. |
| Narutopwn: This is ... ( 1 day ago by Asparition) |
| Narutopwn: This is only good for demonstration. The principle behind THIS motor is that magnetism is turned on and off at specific times to rotate the coil around. Power drives the coil one moment and not the next. It only spins ALL the way around because it gets pushed half way and then does NOT push back the other way because the power is cut by the insulated side of the wire's ends. Nikola Tesla's motor design powers electromagnets as it spins around the WHOLE cycle, which makes it stronger. |
| True, any uniform ... ( 1 day ago by Asparition) |
| True, any uniform fielded magnet would work (but not a horseshoe magnet). I've done the very same years ago with a block magnet. In fact, a permanent magnet is just a simple way to do it. The circular magnet can even be replaced by an electromagnet (yep, even the simple battery hooked up to the nail with wiring tightly looped around it). It just needs the uniform magnetic field nearby to be STRONG enough like SethCasavant said. |
| LOL!! One of you ... ( 1 day ago by Asparition) |
| LOL!! One of you responded with current, the other with power, and the question was about potential (voltage). Granted, my reply is piping up far later, but 1.5 volts is about perfect for this setup on this scale. More voltage on a larger scale doesn't help much because this is really only practical as a visual demonstration and doesn't offer much as an actual motor to do physical work. |
