Solenoid Basics - Part 1

Jeri shows the basic construction of solenoid actuators and demonstrates the relationship between strenght and hold power relative to current flow in the coil.

Thanks for taking the time to do this. People who follow your work know how busy you are and how many projects you are doing ---all at the same time. I am working on a crystalline semiconductor voltaic cell right now and your videos on making a transistor at home have really helped. Thanks.

@Lidmotor I can't wait to see what you come up with.

I WANT THAT T-SHIRT SHE IS WEARING IN THE LAST IMAGE. :O Where is it from?

[jeriellsworth]

@LukeeeeBennettPlus I'm not sure the shirt is still being produced. I got it from a friend Seattle that sold them on his website.

If your trying to build your own solenoid, what is the wrapping pattern for the wire. do you wrap stacked discs of wire along the core or is it one layer up the core then the next layer down and up and down.?

[jeriellsworth]

@zanobi The next video will explore the geometry of the solenoid. I've only seen winding the entire length and then moving up a level.

@jeriellsworth The Classic Eveready 9V batteries had the cat with the lightning bolt tail jumping through the number 9. They still have a smaller logo of the cat on the Everready 9V.

Am I going crazy or do you have Pikachu drawn on those batteries in your diagrams? Lack of sleep is driving me crazy.

What is the unit to measure the force of a solenoid? is it newton, and what is the expected power from that solenoid you were using ? and how can i control the force of "push solenoids", i want to use it as hammer.

Thanks 

[sonicfuker]

That music was pretty gay man. Sorry.

[SalehMagrabi]

where is Part 2 ??

my left ear really enjoyed this video, in all seriousness though, great video Jeri.

[ryantheleach]

my right ear is jealous of my left ear being soothed by jeri's voice.

i am giving this out due to the darn walstreet thing. i have been trying to tell this and every time i build them show tem or patten them, i get blocked. this has been right under our noses. i have now decited it is time everyone knows the truth.

[tcservices1]

now take apart any known coil or transformer realy look at what happens when you apply the field of a goil! you need t do a one way winding! at the ed of the winding or end you go strait down then start the same way. not back and forth. that is why energy crises and free energy is surperessed. they cheet just under our noses! im making a video posting why and when this started.

[tcservices1]

ok here is my big complaint. this video shows truly what i have seen for years. but im making a video and how 3rd world countries wound the coils. thake the drawing to heart! put the polarities on it! and exactly do the same with the coil. ( the kicker) purposly waisting electricity and waist. this is as for motors and transformers! realy look at the coil construction. you will find that they are wound back and forth! each back down winding will cancil out the previously wound sinding!
