    I need to know the best material or ore composite that would reduce the magnetic polarity.I heard of a nickel/iron ratio but did not give the reduction needed.Feed back would be great thank you

    Can you be more specific? What do you mean by reduce the magnetic polarity? You could reduce it to practically zero by using a non-magentic material like aluminium. I doubt this is what you mean.

    Bryan,

    Your question (if that's what it is) is so poorly worded, it's hard to get an idea of what you are asking. Can you restate it more clearly? We can't really give feedback if we can't understand what you are asking for feedback on.

    If you are looking for a metal to shield from magnetic fields, then you probably want -Mu-metal or Permalloy, which are both nickel-iron alloys. Or you can use a superconductor. But that may be impractical for home use...

    My wording was very simple to understand.Thanks Strange,yes a nickel-iron alloys has been the best shield.

    No it wasn't. It was almost incomprehensible. My answer was a lucky guess.

    It generally is simple to understand when you say it. I didn't know what you were asking.

    Bryan, it is not in your power to decalre whether or not what you wrote was clear. That power resides with your readers and two of us think you were almost incomprehensible. That's 100% of those responding to you. The responsibility for clarity of communication rests mainly with the writer or speaker, not the reader of listener.

    Don't be defensive. John Galt has correctly pointed out that the final judge is the listener, not you. Just to be specific about what was incomprehensible about your post, the quality "polarity" is not analog in nature, so one cannot "reduce" it (can you reduce the polarity of a battery?). Strange was able to guess what you were asking only by ignoring the word "polarity" altogether, and speculating on what one might actually seek to reduce. That required considerable cognitive processing, and it was lucky for you that Strange's neural capacity is very large.

    A far better wording would have been along the lines of "how does one reduce magnetic field strength" or "what materials can shield magnetic fields" or something similar. Had you merely reused your thread title's wording in your post, and avoided the word "polarity" entirely, you'd not have confused us.
