Describe the force produced when magnets are brought together, Describe the difference between permanent and induced magnets, GCSE / IGCSE Physics, notes
The electric appliances using a permanent magnet are increasingly demanded to reduce size, weight and power consumption, and therefore to comply with the demands, the permanent magnets are demanded to have higher performance. When the permanent magnet is used for motors of hybrid electric vehicles (...
Does induction weaken permanent magnets? Lets imagine a stationary permanent magnet and a stationary coil, lets imagine that through a procedure, doesn't really matter how, we direct the magnetic field of a pemanent magnet in a way to make it reach the stationary coil in a pulsatile way, th...
As for permanent magnets, it becomes much more challenging due to the requirement of mechanical motion to adjust the positions of the magnets taking into account the large magnetic forces induced by the system. Figure 7 shows examples of permanent magnet based quadrupoles with variable gradient: ...

As a result, grain growth is induced in the main phase at sintering. Here, the grain growth in the main phase causes the coercive force to decrease. The invention has been made in order to solve the above-mentioned conventional problems, and an object of the invention is to provide a ...
Because the distribution of the magnetic field generated by the PMs changes after demagnetization, the no-load back-EMF induced by flux variation in the windings changes accordingly. In the case of uniform demagnetization, the magnetic field still maintains an even distribution. The amplitude of the...
PURPOSE: A magnetoplumbite type ferrite magnetic material and a segment type permanent magnet induced from the same are provided to obtain high magnetic property by forming a sintered magnet. CONSTITUTION: A ferrite magnetic material use... 박길수,김민호,이동영 被引量: 0发表: ...
Accordingly, the billet can be induced and heated at a high temperature within a short time through the arrangement of permanent magnets so the productivity is increased, the electric charge can be remarkably reduced due to improved efficiency, and maintenance and repair of an apparatus are easy ...
