Silverline Magnetiser/Demagnetiser 50 x 50 x 30mm (245116)

Product Information

With it's help you can revive dead or old magnets, or you can magnetize things like screwdrivers, nails, paperclips, or any metal which can be a good magnet. I think the deal now doesn't include the multi-meter but as they are as cheap as chips and I already have one then not an issue as it's still incredibly cheap at twice the price. No more sending off for an 'expert' to do the business or having to use neos soI'm now off to remove all my neos and reinstate the originals. Making a coil is really easy, you need a certain type of wire that depends on what you want to do with that coil. If you intend to learn how to make a coil, you can read this article. Not that this device is useless, it's really a nice proof of concept, but any small magnet can successfully magnetize an iron nail... I am still angered at how many people have negatively criticised this project. The author is a school student and this is only his second project. We all had to start somewhere. Even if the capacitor is rated at 400V, it is never going to charge beyond the mains voltage of 220-240V. There are many un-earthed appliances that rely on plastic insulation to keep the electricity inside, among the most dangerous being hair dryers and hand-held kitchen mixers.

This one is based on an original Meccano design saw the plans somewhere, next stage is source all the electrical components if still available. Getting the roughly the right number of turns is the easy bit, work out diameter of wire, think its 0.018 of an inch divide into length of coil 2 ins, then divide into 2600 which worked out about an inch from inner row. Don't forget to thread though the inner row first, use a cordless drill, great fun watching it wind.Mr Treknology, please stop trying to teach when you obviously know very little about mains AC electricity.

A great piece of kit from a wonderful chap who went to great lenghts to show me how it worked, re-mag'd my ailing horse-shoe Atholl and also showed me his HD layout as well- wow! By pushing the S2 button, a pulse of high current (aprox 50 A) passes through the coil magnetizing the object placed inside the coil. It's a multi tool, idea for magnetising screw drivers etc, I've a 1 inch core solenoid for spanners.a plastic, wood, Plexiglas, or any material you found, but NO metals like iron, steel, aluminum, copper or any metal that are atracted
