Also not mentioned is the newer technology monopole magnets.Well I'm surprised he's not yet been referred to the famous tripolar magnet a la Escher...
So to translate that you just said do it my way and give me the information I want or p--- off - good luck !I do appreciate the responses received. I do also appreciate the time many people have taken in genuinely attempting to assist me.
Certain adverse comments are creeping in and I think it only fair to address them.
I retired many years ago and it certainly has nothing to do with casino business.
I apply logic to everyday life problems and still (even after all the questions) do not see
a) The need to know WHY i am asking the question.
b) WHY no one can give an example of ANY two elctromagets and a device which will change their polarity at a controlled rate.
Now . . . If for some reason which is way beyond my comprehension, no one in history has taken two electromagnets and changed their polarity by a controlling device then I am sorry I have wasted everyone's time. I just fail to see that could be a possibility.
Again, thanks to those who are genuinely trying to help.
See post #5.b) WHY no one can give an example of ANY two elctromagets and a device which will change their polarity at a controlled rate.
I am sure many people have done what you are seeking to do but they most likely achieved that, not through taking something which exists to do it, but through having the means to obtain what is needed to do that. That likely required building the equipment themselves ( using knowledge and skills which you say you do not have ) or commissioning others to build it for them.Now . . . If for some reason which is way beyond my comprehension, no one in history has taken two electromagnets and changed their polarity by a controlling device then I am sorry I have wasted everyone's time. I just fail to see that could be a possibility.
Speaking of logic .... Your refusal to reveal the purpose of your inquiry/experiment implies secrecy, that you do not want others to know what you are up to. Fair enough. I can think of a few of legitimate reasons for non-disclosure. But I can also think of a few not so legitimate reasons.I apply logic to everyday life problems and still (even after all the questions) do not see

A stepper motor and its controller, do exactly that, its how they work.b) WHY no one can give an example of ANY two elctromagets and a device which will change their polarity at a controlled rate.
I am guilty as charged and ashamed of myself. I don't know what will become of me now .....Careful with the language Rex, youngsters read this! (obv not in the rude word filter MMmmm... Technical?).
would not be resonable to assume that an astable 555, not gate and h bridge could do the same job. varible resistor in R2 iirc (its been a long time since i played with 555s')You were offered an H-bridge (or L293) suggestion and you didn't really comment other than appear to request an off-the-shelf solution (Post#10).
If you had Googled H-bridge you would have found that it could (on the face of it) be used to solve your enquiry - in conjunction with some controlling device e.g. PICAXE.
That's the art of delivering something which meets the specification provided, regardless of whether it's what the customer wants or not. Job done, hand the money over. It's for the customer to show it doesn't meet the spec or they have to accept they got what they asked for.How can you draw a schematic when you don't even know about power consumption or configuration of the mythical electromagnetic beast? (Not meaning to be personal.)
Do
toggle (IO pin of your choice)
Pause (a suitable value)
Loop
No-one can advise on what electromagents you need until we know:I .... still (even after all the questions) do not see
