    I'm sure they weren't when I was a nip. I distinctly remember 'experiments' with magnets when we were in junior school where the teacher proved that not all metals were magnetic by showing us that the magnet did not attract coins.

    I've got a new cover for my phone with a little magnetic fastener. When I pull the phone out of my pocket there's 5 quids worth of change stuck to it.

    Maybe they're not suppose to be and I've got a pocket full of counterfeit steel coins.

    They didn't. It's the magnet that is magnetic, coins are attracted by that force. Feel free to tell me to fck off!!

    It depends on the type of coin and when it was produced.

    Magnetic means that which is attracted by a magnet or the magnet itself? Coins would stick to each other if they were magnetic. Or repel, depending on which way the poles were configured? Shirley?

    I'm not saying the coins are magnets, I'm saying they are magnetic.

    http://www.thefreedictionary.com/magnetic

    Ponit three is the pertinent point here: "Capable of being magnetized or attracted by a magnet."

    If a material can be attracted by a magnet it is magnetic.

    My 5ps and 10ps are magnetic too, not just the coppers.

    I was just going to post the same link - The important point here is Mr C has an arts background and works as an artist - so presumably knows nothing about physics.

    Go on then Paul - how would you describe the different effects of a magnet on a steel nail and a brass nail - I would say the steel is magnetic and the brass is non magnetic - how would you describe the difference

    Oil and watercolour? Magnetism exists as a word beyond physics and would generally refer to the attractor, not the attractee. Like that's even a word.

    It wouldn't be a healthy discussion without me crashing in with a wrong answer.

    You'd be surprised though how much relative sciences come into conservation and such.
