Ok - I don't think I will need a spring as this idea could have a few cyclinders, But would the coil of the solenoid shut down and energize fast enough? All I want to do is replace the stationary magnet with the solenoid design then I don't have to worry about shielding. And would it possible to...
Hi guys
Thanks for the answers to my questions. I understand now that using magnetic shielding isn't such a good idea. So I've been having a re think on the idea. In stead of having the stationary magnet at the top, What about an electromagnet to perform the same task but only on the down...
so the idea just won't work at all?
The shield will have to be too thick, the sheild wil have to be a superconductor, and the work needed to move the shield will be wasted.

Thats great
Ok, I am going to carry out an experiment when I have the money. This is what I would like to achive so please bare with me.
I will have one fixed Neo magnet and one sliding back and forth like and engines piston, At top dead centre is when the magnets will be closest (the...
Great , that has clarified it for me.
So If I have it correct, The shielding has a K factor (400K in the example you said). So am i correct in saying that if i had a piece that was 1/4" thick this would be 800K of sheilding? and as in your example, if i places a magnet on one side, will the...
Ok I read something like that on a site, but didnt fully understand it. Is there material that would stop the interaction between the magnets and not replel the magnets.
Or is there a way of neutralizing the magnets say for 1 second? could this be done with an electrical current?

Hi guys
I have a simple question.
The attached picture shows 2 Neo magnets with some Mumetal sheilding between the magnets. Let's say the gap between the shield and the magnets is 2mm. So the overall distance between the magnets is 4mm.
will the magnets still repel from the shielding...
Hi guys
I have question in my homework to rearrange 2 equations. see picture attached.
the equation has to have F as the subject and not have Ev in the equation.
Can someone point me in the right direction please
Gareth
Hi guys
I may have posted in the wrong section.
If I have 2 magnets pushing away from each other (one is fixed) the other is on a crank. And the crank is spinning around 2000 RPM (33.33 crank rotations every second) how will eddy current effect the 2 magnets?
I have Wikied "eddy...
Hi guys
I have calculated the following equation but i need to find a way of testing it.
the info i was given is a diver at 3.7 m height and I need to find the speed at which they enter the water of the pool. Gravity = 9.8 m s-2.
How do i go about testing the equation to see if i have...
