I am doing a science project, where I'm supposed to make something (more or less) useful from a diy electromagnetic motor. I'm thinking about something like a toy car.
The problem is that the motor will be very very weak, and not powerful enough to power really anything.
So my question is how do I make the motor stronger? Is it even possible? Is it another way to make the motor than the traditional way on the image?
>diy
can you explain to me how that motor works?
what's that tire on the bottom?
suggestion: use an amplifier to increase the voltage or something? Idk im just a dumb physics undergrad and I belong on /x/
It's a permanent magnet. I think the magnets magnetic field acts as a opposite force to the currents' (that goes through the coil) magnetic field. Making the coil rotate.
how about a vibrator?
but if it were opposite there would be no rotation
Make a nice windwill of that, focus on the decoration.. makes it so much more magnificent than it actually is, be a good salesman for once.
that shouldnt be spinning, the setup in pic will align itself parallel to the magnet then plop down and stick to it, because those flimsy wires can barely hold the weight of the coil
just make a cooling fan or something. Those are pretty usefull.
Also, if you want stronger motor, you need more power, perhaps a 9v or 2-3 AA's could give you good power.
If you have the tools or resources, you could use gears to make it stronger. Wheels allow you to change speed > torque and torque > speed.
but in reality a diy motor can only do so much...
stronger current
more windings
stronger magnetic field
bigger coil area
making the coild bigger will also add inertia though
