Permanent magnets are materials where the magnetic field is generated by the internal structure of the material itself. Inside atoms and crystals you have electrons and the nucleus of the atom. Both the nucleus and the electrons act like little magnets, like little spinning bits of electric charge, and they have magnetic fields inherent to the particles themselves. There's also a magnetic field generated by the orbits of the electrons as they move around the nucleus. So the magnetic fields of permanent magnets are the sums of the nuclear spins, the electron spins, and the orbits of the electrons themselves. In many materials, the magnetic fields point in all sorts of random directions and cancel each other out and there's no permanent magnetism. But in certain materials, called ferromagnets, all the spins and the electron orbits will line up, making the materials magnetic. This would be your regular iron, cobalt, nickel. Permanent magnets italy mobile number are limited by the structure of the material. And the strongest magnetic field of a permanent magnet is about 8,000 gauss. The strongest magnets here at the Magnet Lab are 450,000 gauss, which would be almost 50 times stronger than that.
Circuit overload
A circuit overload is an overcurrent that occurs when more current (amperage) is drawn than the circuit's wiring can safely handle. If you've ever plugged too many Christmas lights into the same outlet and caused the breaker to trip, you've overloaded the circuit.



Another common type of overload is a surge power draw. This happens when a large motor, such as a refrigerator compressor, draws a surge of power to start up. If the circuit's capacity is exceeded for more than a brief moment, it can trip the breaker. Circuits are usually designed to handle motor startup, and the motor's demand or load decreases after startup, but in some cases, it is still too much for the circuit to handle.
