    Diamagnetism can make levitation possible. How? Diamagnetic materials are repelled by magnetic fields. The most diamagnetic materials are graphite and bismuth. Technically, everything is diamagnetic but the force of it is very weak. Diamagnetism is present in everything, but is only observable if other types of magnetism, such as paramagnetism, ferromagnetism, ferrimagnetism, antiferromagnetism, etc. do not overwhelm it. Most of the time, diamagnetic materials’ effect is very weak. Levitating humans are possible with this, since we are mostly water and water is diamagnetic, but the magnetic forces required would be enormous due to the relatively weak force of repulsion. Overall, diamagnetism sounds pretty awesome, right? Well, it’s a lot…

    If the paramagnetism is cooled below the curie point it could create ferromagnetism, antiferromagnetism or ferrimagnetism. The ferromagnetism is when uncharged metals are attracted to others. Lodestone and iron produce magnetic fields by the alignment of their atoms. When their atoms spin in the same direction they reinforce each other magnetic fields. They have saturation Jupiter Ed https://login.jupitered.com/0/staff.php?sz=a2cd251f&user=619716 2 of 4 12/4/2017, 10:18 PM in the entire…

  • Magnetic Hysteresis Effect Of Magnetoresistance Effects

    The percent change in the resistance of these features decreases as temperature is increased, disappearing above 30K. A positive magnetoresistance feature can also be seen centered at approximately ±0.75T for temperatures of 28K and 30K.. The origin of these magnetoresistance effects is unclear, as NdMo16O44 contains magnetic Nd ions. The paramagnetism associated with Nd-Nd interactions confounds the measurement of the magnetization associated with Mo8-Mo8 interactions―the focus of this…

  • Temperature Dependence Of D. C. Electrical Resistivity

    the Co-Cr nano ferrites were shown in fig .4. Activation energies were calculated from the plots using the formula Ea = 2.303 x kB x 103 x slope (eV) where kB =Boltzmann Constant = 8.602 × 10-5 eV/K A change in slope is observed in the resistivity curve that divides the curve into two regions corresponding to ferrimagnetic and paramagnetic region. Fig.4 Compositional variation of DC electrical resistivity (log ρ) with inverse temperature (1000/T) of CoCrxFe2-xO4(x=0.0 to 1.0) From the…
