WebAs a concrete example, consider Figure 20.16, which shows a charge q moving with velocity →v through a magnetic field →B between the poles of a permanent magnet. The magnitude F of the force experienced by this charge is. F = qvBsinθ, 20.4. where θ is the angle between the velocity of the charge and the magnetic field. WebA switchable magnet works by providing two alternate routes for the magnetic flux that have almost equal reluctance, so you need no force switch from one to the other. One …
Web1 mei 2024 · 1. As the charge has a magnetic moment, it will interact with the magnetic field. When the charge enters the uniform magnetic field, the direction of its velocity changes, while its inherent magnetic field (due to spin) starts to rotate. But the rotation itself doesn't change. This rotation (spin) is the same inside the magnetic field as before ...
