This indicates that, the greater the flux of magnetic fields of a category is, the higher the altitude in the atmosphere is, where they will create an impact and lead to local heating. Conclusions and discussion Sunspots constitute the first historically observed phenomenon among solar activities;...
Fig. 12.9.Flux density (B) versus magnetizing field (H) for the important classes of permanent magnets [43]. 7.2DC motors The two types are (i) brushed and (ii) brushless. The major features of brushed DC motors are shown inFig. 12.10. The coils are wound on a slotted iron rotor wi...
The magnetic field strength H at a point is an axial vector quantity associated with the magnetic flux density in a magnetic field. The unit of magnetic field is the ampere per metre (Am−1), which is the (axial) field inside an infinitely long solenoid of one turn per metre carrying ...

The flux ratio of Te/(Sb + V/Cr) is set to be >10 to avoid possible Te deficiency in samples. The growth rate of magnetic TI or TI films is around ~0.2 QL/min. Finally, the samples are capped with a 10 nm Te layer to prevent their degradation during the ex situ ...
Magnetic helicity is a well-conserved quantity in high-resistivity magnetohydrodynamics as a consequence of Alfvén’s frozen-flux theorem (Taylor, 1974). Berger and Field (1984) have also shown that helicity is still approximately conserved in less ideal conditions. This conservation means that helic...
The design parameters for the hold-off time are: the core material; the cross sectional area; and the number of turns. The hold-off time can be calculated with the formula: ∫V dt=N AeuΔB Where V is the applied voltage, N is the number of turns, B is the magnetic flux density ...
A magnetoresistive (MR) sensor detects a magnetic field through the change of its resistance as a function of the strength and direction of the magnetic flux being sensed by the MR layer. Most current MR sensors are based on the giant magnetoresistive (GMR) effect. In GMR sensors, the resi...
