The capacitor, on average, is capable of holding 3kVDC maybe even as high as 5kVDC. It would have to remain properly housed in the modified microwave oven just in case it exploded. My loco collection is quite small at 7 so I tend to use neo magnets when the originals begin to fade as it's cheaper than having to send them off to a specialist restorer. However as neos can cause greater wear and tear to the bearings and my collection will probably expand over time I'm wondering if Ron may be willing/able to oblige possibly? Fits most screwdrivers including precision screwdrivers, 1/4" Slotted, PH2 Phillips and PH3 Phillips

So using some information about original Meccano magnetiser found some 26 gauge wire and made some coils using 3/8 pole pieces, wire coiled 2600 times. This device is only a PROTOTYPE, so maybe I will try to make a big one that can magnetize your hammer. If you ever feel the need to be bored for an evening start an old biker on the subject of the joys of the motorcycle magneto! 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. Mr Treknology, please stop trying to teach when you obviously know very little about mains AC electricity.

Bunting is the only company to design and manufacture magnetising equipment for magnet assemblies and that manufactures both magnets and magnet assemblies. This unique combination brings together magnet and magnetic design engineers with the ability to design complex bespoke magnetisers for a wide range of applications. Recent projects include a bespoke magnetiser for a global white goods manufacturer and several magnetisers for research institutions and universities.

I cannot begin to tell you how much it has helped our operation, the magnetic filtration unit has been a real problem solver it has surpassed all our expectations. Its cured a 30 year plague!" a plastic, wood, Plexiglas, or any material you found, but NO metals like iron, steel, aluminum, copper or any metal that are atracted The steel has gone through a loop of increasing and then decreasing magnetic fields but the withdrawal step leaves a residual field, thus when you plot the field in the steel you get a loop – that’s the hysteresis loop. If the material follows the arrows in the drawing below it ends up magnetized at the point Mrs.

Now I know Ron Dodd of HRCA builds and sells an excellent magnetiser and has done some excellent YouTube clips. However I can't really justify buying one for one or two locomotives which constantly lose magnetic strength, don't really want to use neo's either. A typical Bunting magnetising system consists of a capacitor discharge magnetiser, a magnetising fixture and sometimes an additional automatic handling system. Bunting Magnetics Europe manufactures both magnetisers and fixtures in the UK to our own standard design or to bespoke customer designs. 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! Tri-ang magnets do not seem to suffer from demagnetisation, though I have found a few. X.04s respond to the same treatment and I've fixed a couple of motor bogies by simply attaching a couple of magnets to the pole pieces. The solution with the Bo-Bo is to copy the prototype and run two nose to nose. For three rail one has to have the wiring or magnet reversed of course. My reversed one is D8017.

It's a multi tool, idea for magnetising screw drivers etc, I've a 1 inch core solenoid for spanners. With the usage of precise meters (Gaussmeter orFluxmeter) and a modified softwareour impulse magnetizers are expandable for magnetic calibrations 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. I usually replace dodgy magnets with a pair of 6mm cube neodymium magnets* padded with a couple of steel washers. A full sized neo. is too strong in my opinion, but I calculated this size should have roughly the same strength as an original magnet and seems to work OK. (3-4 times as strong will require roughly a quarter of the area.)Ihave listed this as “used condition” as it is a homemade article, but all the parts are new and it’s only use has beenin testing and proving the product. Did try the car battery however found just connecting coils up to an old arc welder provided more magnetic strength, not even sure it's pure DC current. However it did work remaging a "problem" Duchess lowering the amps from 0.85 @12v to acceptable 0.60amps @12v Magnetising fixtures are generally custom designed for each application, and therefore should be the first thing to consider when purchasing a magnetising system. Fixtures can be supplied with many different types of magnetisation patterns from simple 2 pole solenoids, to complex multipole systems. As a long time manufacturer of permanent magnets, in particularly bonded Neodymium ring magnets, Bunting Magnetics have been manufacturing magnetising fixtures for our own internal use for many years, and have developed a particular area of expertise in the design of multipole magnetising systems for radial or axial ring magnet assemblies or sensor magnets. Four weeks ago I was searching for an magnetizer that can revive my dead magnets (I killed them heating up at a high temperature, trying to encapsulate in a piece of glass), but I haven't found a instructable project that can help me, so with physics teacher's support I made one that works. volt supply - 5 circuits of a train set 'oval' in 25 seconds for most, hauling 4 SD6 coaches. (Just over 100 scale mph.)

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. By pushing the S2 button, a pulse of high current (aprox 50 A) passes through the coil magnetizing the object placed inside the coil. Worth watching all of Ron Dodds videos, the magnetic direction is important, my pole pieces already have strong magnetic force so getting the magnet the right way is easy they attract, providing of course they don't get put in the wrong way, they are marked.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. Does anyone know if Ron Dodd still supplies his re-magnetiser by special request as I know they are no longer generally available? I wondered myself. I try to aim for all my Dublo locomotives to achieve the specification* speed/load haulage set out in the 'bible', allowing a few seconds for age. Most manage it, but a few excel.
