Power from repelling magnets

[ayeaye]

Field symmetry doesn't need to be considered, because the interaction takes place entirely on one side of the meridian.

Yes, not in case of the gravitational slingshot, this is how it differs.

I want all to get used to the terms "positive attraction" and "negative attraction", these are the only forces talked in this thread. Again, this thread should be named "Power from attracting magnets".

Kolbacict, to measure force, you can just like put a rubber band between two paperclips, and then measure the length of the rubber band under the force. May be inconvenient and maybe not very accurate, but can do. You need some known weights to calculate the length into newtons, like if you have some scales, measure some volume of water or such. But you only need a rubber band and two paperclips. Remember the Hooke's law  https://en.wikipedia.org/wiki/Hooke's_law .

Scales may be a useful tool if you want to measure force between two repelling magnets.
I am not certain what, if anything, it will help you discern in relation to "all magnets".


The more precise your measurement, the clearer the data becomes.
No two magnets are the same.
Even when they are precision specification engineered industrial magnets.
We can make them really close, but they are never the same.
Not only that, many of them are never even symmetrical.
N or S repulsion will show variance, and N-S attraction will vary when you flip them.


You can make your own magnetic repulsion scales by putting the magnet in a clear tube next to a ruler
Fishing scales are cheap, or you can get a precision spring scale at a cookware store for not too much

The thread gets named by the person starting the thread.  And THIS thread is about repelling magnets.  If you want to start a thread with a title about attracting magnets then start YOUR OWN thread.  It is very rude to suggest the title should be changed to something else because you want the thread to be about something other than what the original poster intended.

I'm really sorry but, don't Norman's Lafonte scissors that he last made, use attracting magnets? And Norman started the thread, so it's for him to decide.

I don't think that threads can be renamed, but threads go where they go. Unless Norman decides otherwise, everyone is free to talk attracting magnets in this thread.

What is rude is to come in, and restrict peoples freedom, what they can and cannot talk. By someone who didn't start this thread, and has no right to decide what can or cannot be talked in this thread.

I did NOT say we shouldn't talk about attracting magnets or anything else for that matter.  I think it is rude to keep insisting the name of the thread is wrong when you didn't start the thread.
