Our school used this video and told us to write a lab report on it. Glad it was the 1st video when I searched “ How to construct a simple electric motor”. Thanks sir it is easy to understand and well demonstrated.
why did you remove the insulating part of the copper wire for the copper loop? I believe it is to act as a commutator like in an actual d.c motor. But I'm not sure how it works. Can u explain? Thks
I wish I saw this comment sooner but if you're still trying figure out why he removed the insulation from the ends of the copper wire, this is so that he can create a circuit and electricity can flow from the battery through the copper wire. this is necessary because if you keep the insulation on the ends of the copper wire, for example, the coil won't spin because there's no electricity flowing through the copper wire. if you look closely, the ends of the copper wire are connected to the battery by another line of wire in between them.
If the thin copperwire breaks while building my motor, can I re-usethe copper wire together? Please sir answer my question quickly because it is my school project there
HI, I teach in China at an international school and our access to RU-vid is often blocked. May we have your permission to download this video and host it on our local media server IN our school? We will link back to YT source.
can u reply the one really important question which is that , after you fully removed the insulator part of the coil's end, how the heck did coil manage to spin in one direction only. because when I analyzed it, after 180 degree, the net tork changes in opposite direction which makes coil impossible to turn in one direction within that RPM's. what it should be doing is, turning in one direction and then other and so on.
it's probably because of imperfect balance of the coil. one half of the spin, it's closer to the magnet, and with the other, it both is farther (less magnetic force is applied) and also it "jumps high" due to centrifugal force, and it loses the contact entirely.
You’re missing a very important step: insulate half the wire on each end of the coil. Since you’ve removed the entire amount of insulation you must have used a permanent marker to temporarily insulate part of the wire ends. Is that what you did to make it spin?
@@dariogrosse5053 As the coil flips, the electric current effectively changes direction in relation to the magnetic field, therefore counteracting its rotation. You'd only see the coil seesaw back and forth if one side wasn't insulated.
Can you help me? I cannot find a cable that has one thin wire inside Its only more wires, or one wire but thick So where i can find wire just like in your video
How can this work without alternating current in the coil? This is impossible. The coil will just become dipole magnet, move to align itself with the magnet below and stop.
