    If I put a piece of Iron by a magnet, it's attracting pole, will force the the iron to attach to the magnet - true or false?

    If I put a piece of Iron by a magnet, it's opposite pole, the the iron will not attach to the magnet - true or false?




    If I was too put two magnets together, reverse polarities, leaving a small gap, then tried to put the iron into the gap, the iron would be deflected?

    True.

    False. Both poles will attract a piece of iron.

    Both magnets would stick to the piece of metal. (Depending what you mean by "reverse polarities", I suppose.)

    This one is simple enough that you should just try it and see. Go by Hobby Lobby (or wherever) and get a cheap horseshoe magnet so it'll be easy to hang something in the middle.

    Agree with both answers. But by all means get some magnets and play with them, just cause they are fun.

    I've never seen the attraction in magnets.

    Obviously your magnetic personality is the wrong polarisation

    Here goes Bob again pouncing on other's posts. Anyway my question: Take a bar magnet attract a bar of iron to either pole. The end, of the bar is now magnetic? Is there a loss of magnetic power? If so what would be the distance/power relation? Then if you put the same pole of a differant magnet to the end of the iron bar would it repell?

    Agree. Get some magnets from Stanford Magnets or whatever will help you figure out things immediately.

    Where does the kinetic energy that moves metal in a magnetic field come from? What kind of energy transfer is taking place when a compass needle spins or a piece of iron is pulled across a table?

    As I understand it, the same way a body has potential energy due to it's position in a gravitational field that can be converted to kinetic energy when it is dropped, magnetic materials have potential energy in the presence of an electromagnetic field which can be converted into kinetic energy when they are allowed to move in the field.
