Build a simple electric motor with just a battery, magnet, paper clips, and coil of wire in this fun science experiment! Written instructions are available on the Science Buddies website: www.sciencebuddies.org/scienc...
A kit is available with most of the parts you need for the experiment (some parts must be purchased separately, see written instructions): www.homesciencetools.com/prod...
To purchase the materials individually (note: these are affiliate links. All proceeds help support Science Buddies, a 501(c)(3) nonprofit, and help us keep our resources free for everyone):
- Small neodymium magnets, approximately 1/4" or 6mm in diameter: amzn.to/2Wytg6n
- Enamel-coated magnet wire (exact gauge is not critical): amzn.to/2EJfEuW
- D batteries: amzn.to/2QBL1wb
- Jumbo metal paper clips (not plastic coated): amzn.to/30WO5Yj
- Electrical tape (other types of tape will work): amzn.to/2W1FwYw
- Fine-grit sandpaper: amzn.to/2QxCpqq
Note: there is a small typo at 0:40 in the video. That should be 3 cm (centimeters) of wire, not m (meters)!
Science Buddies also hosts a library of instructions for over 1,000 other hands-on science projects, lesson plans, and fun activities for K-12 parents, students, and teachers! Visit us at www.sciencebuddies.org to learn more.

Finally i do understand how an electric motor works. It was not until a fan in a laptop broke, that i learned how a motor works, same as a engine, it needs a timing when there is 0 energy. All motors need a commutator whether its mechanical or electronic, it's the same principle like the valves of a 4 stroke engine. In this example the commutator is the moment the force of repelling makes the rotor to do half a turn, because there is an input energy higher than the needed to push the coil, it goes to the state of 0 and beyond and gravity does the rest, i wonder if you can make this with a flywheel but i assume it would be very inefficient than just using a commutator that switches the polarity of the coils. So, all motors are alternating current devices.

@theamaturepro 8 месяцев назад

Does it have to be a copper winding or could I use a copper crush washer and solder a coper rod accost it? I guess what I'm wondering is if it's the mass that matters to act as a load or if the individual wires play a part?

@Science.Buddies 8 месяцев назад

The coil of wire acts as an electromagnet, generating a magnetic field that interacts with the field from the permanent magnet. Since the wire is insulated and coiled into a loop with multiple turns, it generates a much stronger magnetic field - you wouldn't get the same effect if you just soldered a washer to a single straight wire.

We don't recommend using a 9V battery for this project. The + and - contacts of a 9V battery are on the same end, so you can't follow the exact same directions to physically assemble the motor. The 9V battery's voltage is also much higher (9V instead of 1.5V) so you may burn out the very thin wire.

@@Science.Buddies Yes thank you, I managed to make an electric motor using the 9 volts battery because I didn't have neodymium magnet that could stick to the side of the 1.5 V battery, but it could to the 9 Volt one. It was more complicated than the one you made in the video but in the end mine works too, but the video was pretty useful too, I wouldn't have been able to make one without your video so thank you!

Hi! What was the size of the magnet po?

@Science.Buddies Год назад

See links in the video description - the magnets are approximately 1/4" or 6mm in diameter.

Will my electric motor work if I use 2 battery 🔋 1.5v × 2 = 3,0v

Hi - yes, this project should work if you combine two batteries in series, but you need to be careful not to burn out the thin wire. You should only run the motor for short periods of time.
