Magnetic substance definition
WebSubstances for which the magnetic susceptibility is positive are classed as paramagnetic. In a few cases (including most metals ), the susceptibility is independent of temperature, but in most compounds it is strongly temperature dependent, increasing as the temperature is … WebWe define a Magnet as an object that can create an invisible magnetic field that to cause attraction of opposite poles and repelling of similar poles. Further, the magnetic field comprises an orbital section around which the electrons spins. The force produced as a result causes two objects to attract or repulse without converting into a magnet.
