Block Neodymium

Is there something that is not power that could block a magnetic field?
I'm doing a little experiment with my son for a science project and we are looking magnetic resistance in typical household items. We have not found anything. Glass. plastic, paper, water, nonferrous metals, the wood, whatever. Of course, depends on the thickness of the material and the magnet. We are working with neodymium magnets.
Several nickel-iron (plus some other impurities, as molybdene) alloys that can do that: MU-metal, permalloy, supermalloy, nilomag, sanbold. Mu-metal is often used for shielding magnetic fields on appliances.
Many of us know very little about magnets. Remember the basic science experiments elementary school, designed to teach about the fundamentals magnetism. Some of us might remember that magnets have two poles. But for many people, not involving magnets in our everyday lives, we are not even aware what a great role to play in our world. Magnet technology has come a long way in recent decades. In today's world, imams are hundreds of applications, including telecommunications, radar systems, computers, satellites, automobiles, and more. We will explore are some uses of magnets that the person average could not be considered.
Most of us know that magnets are used to collect certain types of metal. Construction companies typically use large magnets to collect the hazardous metal waste on construction sites. Sometimes these magnets are electromagnets high technology and sometimes plate magnets are most basic may be suspended from the front of a vehicle or forklift. vehicle mounted "sweeper" are also magnets sites used in new home construction. For example, a roofing company might roll a sweeper magnet through a homeowner yard for collect all the stray nails done once the roofing job.
Another common industrial use of magnets is in the conveyor system. magnets conveyor can be used to remove traces of metal material in a conveyor system. An example of this could be a plastic recycling company is moving plastic parts by conveyor belt to a mill. If a small piece of non-ferrous metal is introduced into the mill, milling head opaque. Worse Moreover, if a larger piece of metal entering the mill is likely to break the whole machine, and could even pose the threat of metal debris in the area of work. In most of the plastic recycling facilities, transport of a magnet will be hung directly above the conveyor belt to pick up the pieces metal that can be mixed with plastic.
The power of magnets has been used in many high technology applications, too. One of these the high technology of magnets can be found in a new type of windows for residential use. A Japanese company, Micro Reactor Systems, has recently introduced a window that self-darkens to provide privacy for the owner. Liquid crystal molecules are embedded between two thin layers of glass, and magnetically polarized to react when a power supply is on or off. When the device is off, the glass is transparent. However, when a low voltage of electricity is selected, the glass becomes opaque, blocking light and providing privacy. Although this is a new technology at this time and is very expensive in the coming years, probably will be very common in both residential and commercial applications.
The uses of magnets are incredibly large and learned lot about how to harness its powers. The magnets are already used in the production of almost all products we use. If you have a cell phone or a car, you are relying on the magnets for these work items. Magnets are also widely used in health care. Almost all major hospitals at work has an MRI machine. This important medical test is based on magnets to show detailed images of the human body. It's amazing how much we know about magnets, however, is even more remarkable how much we have yet to learn. Scientists discover new uses for magnets and new information on magnetic properties of each day. Although we can not predict what new inventions or innovations are coming, we can be sure that the magnets will continue to play a role important in future technologies.
