2009年4月26日 · First thought was a water softener but this has ongoing costs so I took a chance on a UK system which produced a magnetic field round the fresh water inlet pipe. A small diameter cable is wound round the pipe for about a foot or so.

2009年4月27日 · In this Question of the Week, we find out if a magnetic field can stop pipes from clogging up with limescale? Many manufacturers would like us to believe that simply clamping a magnet to your plumbing is all you need for clean, free flowing water, but …

2010年1月12日 · I suppose a sufficiently strong magnet could in principle change the crystal structure if the field extended right through the boiler (since water is slightly magnetic), but the ones that they try to sell you that clip onto a pipe, before the boiler, it just can't work- the water would be disordered by Brownian motion within a few microns of ...

2008年5月5日 · The are lots of firms flogging these magnet things and other devices. Just one..... """"The Ethos MAXPower Fuel Saving Unit is an incredibly powerful, heavy duty, fuel conditioner that simply attaches to your vehicle's fuel line, without the need for any tools or pipe cutting, and increases your miles per gallon (m.p.g. & l/100Km) by an ...

2009年3月6日 · as long as you dont use glass as a core, you should be ok, coiled wire itself can make electromagnet, tho weaker than solid metal core one. the core does not need to be a block or rod either, you can do laydenic kind of magnet by this way: wrap insulated wire around spring coil that is made of copper, insert a NON conductive material pipe ...

2010年10月8日 · The train starts out rolling forward on wheels but as its speed increases, the track begins to become magnetic. That's because whenever a magnet moves past a conducting surface, electric currents begin to flow in that surface and electric currents are magnetic. Thus the moving magnetic train makes the aluminum track magnetic.

2012年8月6日 · What you need is a length of copper pipe and a fairly strong magnet that can fit in the pipe (neodynium magnets work well). If you hold the pipe vertically so that you can drop the magnet straight down the center, you'll notice that the magnet slows down when falling through the pipe, as if its resisting gravity.

2006年7月10日 · This effect, if it is there at all, is transient (i.e. if you are using this device on a pipe leading into a tank, and the water is left standing in the tank for hours or days before being used, the effect will have been lost – it only claimed to work if you use the water fairly immediately after it has passed through the coil.

2008年9月7日 · Guy - First of all to be able to make a beam circulate round the LHC you need a vacuum pipe. Inside the vacuum pipe you need an ultra high vacuum. The vacuum of the LHC is about 20 times lower than the pressure on the surface of the moon. Once you have a beam circulating you need to keep it on its circular trajectory using very strong magnets.

2017年12月15日 · Yes, they would push on each other - but if you have ever used a magnet as a compass, you would know that the Earth's magnetic field is very weak, so the force of repulsion is very low. There are other places where the magnetic field is stronger, such as the vicinity of Jupiter or the Sun.
