Magnet force shield

[conradelektro]

Lets look at a test device which can test your distance time beliefs.

Test device parts needed:
A DC electric motor which has a flywheel attached to its shaft and use of photo switch to turn the motor on and off.

First test:
We attach a scale to the outer circumference of the flywheel and adjust the current to the motor so it can pull 34 grams. Then we adjust the photo switch to power the motor 110 mm distance of the flywheel outer circumference. We note of the RPM in this condition.

Second test:
We attach a scale to the outer circumference of the flywheel and adjust the current to the motor so it can pull 538 grams. Then we adjust the photo switch to power the motor 11 mm distance of the flywheel outer circumference. We note of the RPM in this condition.

If your belief is correct, the RPM should be greater on the first test compered to the second test, correct?

Luc,

I can not answer this question just like that, I probably make an error. And I do not want to put more work into this, I lost already too much T I M E.

Yeah TIME, and loosers, right.
Forget about time. It's a fog granade. Conrad just seems to insist on being correct, although already being prooved being wrong, which he temporarily agreed with.

With your bicycle you can drive with a high or low gear from town A to town B. If you dive with little force, it takes less force over a longer period of time, if you dive fast it takes more force over a shorter period of time. Total energy used is eighter time * force OR distance * force. Every discussion about this subject seems like good ol merry go round to me.

furthermore, rotational vs straight push is of little meaning since the Radius of the wheel is really big.

What is still a question is how the 11mm push is measured over that distance, with the wheels' magnet aligned in the center, or with it passing by.

Dieter, please come to your senses.

An eight Watt lamp switched on 2 hours needs the double power or energy than being switched on only 1 hour.

8 Watt switched on 2 hours is 16 Watt-Hours.

8 Watt switched on 1 hour is 8 Watt-Hours.

8 Watt switched on 57,3 hours is 458,4 Watt-Hours. (Really difficult?)

Please, please, please, you may call me whatever you want, but please say that this is correct. This is not a fog granade, it is the simple truth.

Sorry Floor for the off topic posts

Yeah, Floor, sorry. I was lured into this off topic stuff ^^
Just this: Conrad, face it, your lamp comparation is silly. Light a lamp for an hour, the light and heat energy output will be half of two hours, no matter how fast you throw the lamp out of the window. Or something.


So lets get back to shielding, that I am personally very interested ATM. Thanks Floor, very interesting.


The problem I am currently confronted with is that a shield will adopt a polar axis that is aligned to its shape, usually 90deg to the magnets axis. In my particular design this leads to the undesired sideeffect, that an approaching shield is repelled by the coils reactive field:
pm:
N
S
shield:
    <<<N===S
coil:
N
S (due to decreasing primary fieldstrength by progressive shielding)


Which I try to overcome with a big, ultrathin PM at the bottom of the shield, facing NS downward. Unfort. I didn't find useful magnets on ebay, maybe see also my "Buddy" Thread.

Exactly what I am saying, nothing more an nothing less. It matters whether you switch on the light one hour or only half an hour. This is my point and you repeat it like I said something else. Strange!

And this is not off topic. It is very important what one compares when calculating input and output POWER (or energy).


FORCE

WORK = FORCE * DISTANCE

POWER = WORK over TIME


And one compares output-POWER and input-POWER (not FORCE and NOT WORK).


I know, some do not want to listen, so be it.
