To distinguish this approach, one might speak of the 'full spherical flux density'.
The flux density is increased near the edge of the paraboloid.
Focusing effects again result in an increased flux density near .
In this case the region will have a finite but depleted flux density.
The power loss is measured as a product of magnetic field and flux density.
The flux density, on the other hand, will be different on account of the relationship.
We shall therefore take the flux density in the gap to be equal to B0.
What current is required to produce the same flux density after a gap of 0.5 mm wide has been cut in the ring?
What flux density is produced in the gap by a current of 7.5 A?
The flux density of high performance permanent magnets is limited.
