Magnet producing some friction material may be a magnet material is not iron, is steel round magnet, but not all can be made of steel magnets, because they contains its material, stainless steel can not act as a magnet. We manufacture magnet with a screwdriver and the material you need, take a magnet to metal parts rub screwdriver magnet, from one end to the other end, they repeated friction force solenoids, you can create a magnetic screwdriver. Most magnetic orientation direction of the magnet can be magnetized concept to saturation in the same direction, that direction is called "a magnetization direction" (direction of orientation). No magnet magnetic orientation direction (also called isotropic magnets) than orientation magnets (also called anisotropic magnet) is much weaker. Key transferred powerful magnets allow small gap in the key is not difficult to make powerful magnets are not transferred to a small gap in the difficult "to do"? Using a wire hook up with string ah in that word to help a magnet sucked out with tweezers or small wire like slowly pick up. I tried once. Success. If possible, try to use a magnet. It is not that you will find a neighbor magnet pieces, or to find the fire (call 119), explain the situation, I think it would pipe. I wish you good luck. Powerful magnet wire with a small dig · I've been doing! ~ Slowly dug a thin wire, do not worry! Preferably have a strong magnet would be better filter network has blocked off, because change did not fall air conditioning inside. You put the hook in front of the hood open (no screws, breaking his hand on both sides) should be able to see your beloved, then the key is not to remove the filter network to reach out to touch inside.
