magnetic
In electromagnetism, when two magnets or magnets are attracted or repelled to each other, or when the current-carrying conductor generates a magnetic field around it, the magnetic needle is deflected, or when the closed circuit moves to a non-uniform magnetic field, there is a current in the closed circuit , These are related to the phenomenon of magnetic. Any magnetic-related phenomena will also be related to the magnetic field. Magneticity is the property of the material in response to the magnetic field. Each substance is more or less affected by the magnetic field. Ferromagnetism is the strongest and most well known magnetic. Due to its ferromagnetism, magnet or magnet produces a magnetic field. In addition, the paramagnetic material will tend to move toward the strong magnetic field, that is, by the magnetic field to attract; diamagnetic material will tend to move toward the weak magnetic field, that is, magnetic field rejection; there are some substances with the magnetic field There are more complex relationships, such as the nature of spin glass, antiferromagnetic, and so on. The effect of external magnetic fields on some substances is very weak. The magnetic state of matter is related to temperature, pressure, external magnetic field, etc., depending on the temperature or other parameters, the material will show different magnetic properties. ...
