Based on this, the optical drive rotation phenomenon of the circular pyrolytic graphite on the nested cylindrical permanent magnet is calculated, analyzed, and explained. It is found that when the nested cylindrical permanent magnet is strictly coaxial, the circular pyrolytic graphite sheet will not rotate under laser irradiation.

Magnetic Susceptibility Imaging as a New Approach towards Characterization

Graphite is one of the most diamagnetic substances at ambient temperature. Images of pyrolytic graphite slivers hovering over neodymium magnets are well known. Fig. 3 shows the results of a scan on a block of (regular, non-pyrolytically grown

Magnetic Levitation System Using High Temperature Superconductor and Soft Magnetic

passive levitation of PM by HTS and Pyrolytic Graphite (PG) and some applications of passive levitation, for examples passive bearings, vibration isolator and maglev are described. Chapter 4 discusses about levitation techniques in which ferromagnetic material

Magnetic levitation

Diamagnetic levitation can be used to levitate very light pieces of pyrolytic graphite or bismuth above a moderately strong permanent magnet. As water is predominantly diamagnetic, this technique has been used to levitate water droplets and even live animals, such as a grasshopper, frog and a mouse. [11]

DIAMAGNETICALLY LEVITATING THREE PHASE MOTOR WITH

Marquez et al. (1999) have investigated this application of levitation in the area of multi-pole motors with levitating rotors. As discussed above, levitating rotors pro-vide an advantage of frictionless rotors and hence lesser energy losses due to friction.

LEVITATION SOLUTION FOR A CYLINDRICALY SYMMETRIC RING

cylindrical symmetric ring magnet. 1. INTRODUCTION The Earnshaw's theorem [1] prohibits the stable static levitation of permanent magnets in stationary fields with no energy input. However, by a proper placement of a piece of diamagnetic material (plate or
