    Greetings dear electricians!

    If I had a larger core what would that effect?
    I wanted to build to electromagnets with equal strengths + magnetic field.
    But different sizes, can I do that?

    What would you all recommend me doing?


    Thanks,
    - Moha

    Your question is confusing.

    It all depends on how you measure "strength". Is it by flux density, or total flux (for example)

    If the former, you have a core that narrows to a fine tip to concentrate the flux. To make them have the same flux density, for a given number of turns and current, the end of the core should have the same area.

    But this is not electronics, it is physics and I would STRONGLY advise you to ask on a physics forum.

    Also, not many of us are electricians.

    Good advice. Should find an alternative.

    Strange.


    Thanks though!

    Electrician, at least in the U.S. is someone who works with residential or industrial electrical power, not electronic circuits.
