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.
The electromagnet is positioned in a constant magnetic field created by a permanent magnet. These two magnets -- the electromagnet and the permanent magnet -- interact with each other as any two magnets do.n this way, the alternating current constantly reverses the magnetic forces between the voice coil and the permanent magnet. This pushes the coil back and forth rapidly, like a piston. When the coil moves, it pushes and pulls on the speaker cone.
