Acoustic absorption refers to the process by which a material, structure, or object takes in sound energy when sound waves are encountered, as opposed to reflecting the energy. Part of the absorbed energy is transformed into heat and part is transmitted through the absorbing body. The energy transformed into heat is said to have been 'lost'. When sound from a loudspeaker collides with the walls of a room part of the sound's energy is re… WebbHysteresis Loss. Definition: The work done by the magnetising force against the internal friction of the molecules of the magnet, produces heat. This energy which is wasted in the form of heat due to hysteresis is …

Thus providing the user a fair chance to carefully select the material used for making permanent magnets. Webb8 juni 2009 · Hysteresis effects originate from the alignment of how the electrons spin around the nucleus in a magnetic domain. For each domain there is a reversible and irreversible rotation, which corresponds to a reversible and irreversible magnetization ( Ref. 1 ). In a magnetic material without hysteresis losses, there is only a reversible part of the
