aThe motor is simply a battery, a magnet, and a small coil of wire you make yourself. There is a secret to making it (which I will of course share with you) which is at the same time clever and delightfully simple. 马达简单地是电池、磁铁和您做自己导线的小卷。 有秘密到做它 (当然...
If you do this arrange the magnet so it is the other way up to the bottom magnet. You now want to bend your piece of wire, so that it goes from the centre of your nut, making a contact with the positive end of the battery, to touch onto the side of the magnet and complete the...

However, if you drive a hybrid, you want to use the brakes as this is what regenerates power for the battery. #10. Don’t Abuse Your Car Most car owners drive like they are in the Indianapolis 500. While it can be fun at times to drive fast, know that the harder you drive, the...
In summary, the conversation discusses the design and efficiency of a simple electric motor using a D cell battery, copper wire loop, and a magnet. The individual has found a way to make the wire loop spin using current and a magnet, but is looking for a design that allows for current ...
(atoms with too few or too many electrons) are formed from the materials in the electrodes and take part in chemical reactions with the electrolyte. At the same time, electrons march from one terminal to the other through the outer circuit, powering whatever the battery is connected to. This...
