A rotating coil - Collins.co.uk.
... The definition of magnetic flux Φ = BA applies specifically to a situation where the magnetic flux density B is normal to area A (as in Figures 17 and 18). However, in a situation where the magnetic flux density is not normal to the area of the coil (as in Figure 19a), it is often necessary to deter ...

Braking Index of Isolated Pulsars
... Given that the most accurately measured braking indices are for “slow” rotation, and span a range of values from 1 ~ 2.8, it may be interesting to consider a braking index which may be a combination of more than one mechanism. Expand the braking law by a polynomial: Ω̇=−s (t)Ω−r (t)Ω3−g (t )Ω5 ...

... It is not soft to the touch. Iron is a magnetic material, but in soft iron the material is made up of small domains, each with its magnetic field pointing in a different direction. So by itself, soft iron does not make a good permanent magnet, because the fields from all the differently oriented dom ...

Neutron stars are strange and fascinating objects. They represent an extreme state of matter that physicists are eager to know more about. Yet, ev ...

... But if the magnetic moment arises from the motion of an electron in orbit around a nucleus, the magnetic moment is proportional to the angular momentum of the electron. The torque exerted then produces a change in angular momentum which is perpendicular to that angular momentum, causing the magn ...
