How is a magnet magnetized
WebIn fact, it is possible to re-magnetize a magnet with one whose force is greater, such as the powerful neodymium magnets, which are made of neodymium, iron and boron; also with a rare earth magnet or with the sum of several old magnets, however, the polarity (south and north) must first be determined and the correct pole magnetized. Web13 apr. 2024 · Abstract. We investigate two-temperature accretion flows onto strongly magnetized compact stars. Matter is accreted in the form of an accretion disc upto the disc radius (r d), where, the magnetic pressure exceeds both the gas and ram pressure and thereafter the matter is channelled along the field lines onto the poles.We solve the …
