HOMOPOLAR Motor That Can Be Made at Home

About: I am 14 years old and am just starting out and I plan to be an engineer

This is an instructable that will show you to make a motor out of things you have lying around the house

Step 1: Materials

D-battery, Flat magnet, Rod of some sort(I used a screw), Copper wire, Casing(optional), Flat thin piece of plastic(optional), Switch(optional),

Step 2: Assembly

Put the screw on the negative part of the battery. Next you need to put the magnet on the screw head(you see why I use a nail) and finish the circuit by attaching the wire to the positive part of the battery and touch/attach the other end to the magnet

Step 3: Optional

After everything else you may get casing and use a switch that will move the plastic in between the wire and positive section of your battery cutting off your circuit saving energy and making practical use possible (sorry but I have no pictures of this)

Step 4: WARNING

this motor can fly apart if not secured and you'd probably not like a screw in the eye

Hi, i plan on doing this for a physics assessment. My dependent variable would be the angular speed measured by a laser tachometer but for my independent variable i wanted to do voltage but we need at least 7 different sets, so 7 different voltages. I'm not sure how to do this, should i find batteries with 7 different voltages? use a variable power pack? or find another independent variable? thanks.

Just commas you say? What about getting rid of the double negative of, "no way that will never work"? No never means always. What would be proper would be, "no way that will ever work".

i saw this on youtube a couple of years ago and thought "no way that will never work" I was really surprised when i tried it in not only worked but worked really well.
