Most broken toes heal well, usually within four to six weeks. Less commonly, depending on the precise location and severity of the injury, a broken toe may become infected or be more vulnerable to osteoarthritis in the future.
A permanent magnet generator is a device that converts mechanical energy to electrical energy. In this device the rotor windings have been replaced with permanent magnets.These devices do not require a separate DC supply for the excitation circuit or do they have slip rings and contact brushes.he demand for these devices is increasing day by day. With the increasing cost of electricity people are looking for an alternate source of energy and the permanent magnet generator perfectly fits in that place. These devices do not use any environmental resources to produce energy and thus are environment friendly.
A permanent magnet is an object made from a material that is magnetized and creates its own persistent magnetic field. An everyday example is a refrigerator magnet used to hold notes on a refrigerator door. horseshoe magnet made of alnico, an iron alloy. The magnet, made in the shape of a horseshoe, has the two magnetic poles close together. This shape creates a strong magnetic field between the poles, allowing the magnet to pick up a heavy piece of iron.
