I don't understand how the tightly compressed coil where the loops are touching each other still produces a magnetic field. Why doesn't the current just go across both sides of the coil, since it's basically just a circle?
@electricandmagneticfields2314 12 күн бұрын
It is magnet wire. There is insulation on the wire. The insulation had to be removed at the two ends to attach the battery. I use a 9V battery when I demonstrate this in class.

I purchased that coil from a company called Pasco, www.pasco.com/products/lab-apparatus/electricity-and-magnetism/coils-and-cores/primary-and-secondary-coils#desc-panel It does not say how many turns on that outer coil. I used several rare earth magnets stuck together. So the strongest magnets I could find.

Sounds dumb but can we create car brakes with this?
@kettenschlosd Ай бұрын
they are used in breaks for high speed trains and rollercoasters actually! so your idea isnt that unreasonable. i think one problem would be that for a car, you wouldnt want a dead battery to mean no breaks if its an electro magnet. (i think permanent megnets would be too much extra weight). also a car break with this mechanism would "feel" different especially with low speeds while parking for instance. the sharp breaks of friction based technology probably make for tighter control. its a fascinating idea though. i deffinetly wonder if its been tried for cars.
@kongol5036 Ай бұрын
@@kettenschlosd Oh cool! Thanks for sharing. And maybe they can create a hybrid system, magnet brakes with faster speeds like on the highway and then it switches to a mechinal one at mechanical half way. Or if no electromagnetic power, just defaults to your mechanical brakes. Regardless, this is cool technically and never knew that roller coaster utilize this

So I was playing with a Van degraaff generator 40 years ago ( and the discharge spark was about 11 inches) I put out my fist and let it discharge on the tip of my (bird finger) knuckle about 8-10 times and the next day I had a water blister 1/4" x 1/4" in the same spot. I guess the spark made quite an impact.

3:43, why there is no electric field inside the conducting plate due to the "static situation"? Also, the electrons move initially (until the electrons move) due to induction, causing current flow (top to bottom) right?

A very long time. It depends on the leakage current through the glass insulator. I am guessing for years. That is why capacitors in electronics like old CRT TVs and microwaves can be dangerous.
