Flux-modulated-type magnetic gears are suitable for such high-speed applications because of their non-mechanical contact and high torque density. However, eddy current loss in magnets must be ...

\(power \ of \ a \ lens \ (D) = \frac{1}{focal \ length \ (m)}\) A lens has a power of -3.33 dioptres. Calculate the focal length and state what type of lens it is.

However, when there is less residual magnetic flux in iron core ... especially solving the problem of low measurement sensitivity under small residual flux density. The proposed method was ...
