Depending on the composition of the stainless steel, a magnet may or may not stick to it. Stainless steels are alloyed steels containing iron, carbon and other components. The iron is strongly magnetic, but the other components interfere with the iron atoms' ability to line up in the same direction, which is what gives it strong magnetic properties.
Some components interfere more than others. For example, stainless steel that contains chromium — often used for kitchen knives — is still somewhat magnetic, while stainless steel that contains nickel — such as in kitchen sinks — is not magnetic at all. Other alloying elements used in stainless steel include molybdenum, manganese, silicon, copper, nitrogen, niobium, titanium and sulfur.Learn More
Factors that can make a electromagnet stronger are increasing a coil's current flow, adding an iron core and increasing the number of turns to a coil. Building an electromagnet involves wrapping a copper wire around an iron core like a nail. A battery is then attached to this setup so that a current can flow through it.Full Answer >
An AC generator, also called an alternator, is a device that converts mechanical energy into electrical energy. "AC" stands for "alternating current." The device generates alternating voltage by rotating a coil in the magnetic field.Full Answer >
Tin is magnetic in the literal sense of the word. The effect is so weak that it could be considered non-magnetic for all practical purposes. It is called a paramagnetic substance scientifically, but it has such a weak effect that it can be compared to a diamagnetic element.Full Answer >
Magnetic levitation is a method of supporting an object with the repulsive force of magnets and the stability of servomechanisms. The object is thus suspended in the air, counteracting the effects of gravity.Full Answer >
