A magnet is a neat scientific anomaly. Magnetic attraction is caused by the positive and negative atom particles in an object to line up all together. When the negative and positive particles stay on their designated side, they are polarized. This causes an attraction because negative attracts positive. Magnets are not only fun to play with, they are also handy. In fact, many screwdrivers and tools are magnetized to help pick up screws and nails in hard to reach places. Enameled wire is made of copper with a thin dielectric coating. Conventional wire can be used (PVC or polyethylene) but you will not get the same turns density. With bare copper you can only have one turn or be careful to space the turns to avoid shorting. Copper is used because it ductile and conductive, the wires must be insulated from each other, if not your would have one thick coil instead of many separate coils.aluminum coated copper wire for Relay Argentina Resistance alloy with moderate resistivity and low temperature coefficent of resistance with a flat resistance/temperature curve over a wider range than the "manganins". Constantan also shows better corrosion resistance than the man ganins. Uses tend to be restricted to ac circuits. Constantan is also the negative element of the type J thermocouple with Iron being the positive; type J thermocouples are used in heat treating applications. Also, it is the negative element of the type T thermocouple with OFHC Copper the positive; type T thermocouples are used at cryogenic temperatures. Product characteristics and application: all kinds of flat aluminum magnet wire in Kenya This product can work continuously at 155 °C and 180 °C environment, has good welding resistance, high performance, easy coloring, and the purity of the highest grade of copper, with high tension, low resistance and other characteristics, mainly used in the high precision instruments, aerospace technology, a micro electric appliance
