Appendix A. The Normal Geomagnetic Field in Hutchinson, Kansas ( ) Model: IGRF2000
... A magnetic declination of 12 degrees West means that magnetic North lies 12 degrees West of true north. True bearing = 72 degrees + (-12 degrees declination) = 72 degrees - 12 degrees declination = 60 degrees East It should be noted that the magnetic declination becomes undefined at the North and S ...

... A heavy pulley, with radius R, starts at rest. We pull on an attached rope with constant force FT. It accelerates to final angular speed w in time t. A better estimate takes into account that there is friction in the system. This gives a torque (due to the axel) we’ll call this tfric. What is this b ...

Magnetic Properties
... There is no magnetic dipoles in the absence of a magnetic field and when a magnetic field is applied the dipole moments are aligned opposite to field direction. The magnetic susceptibility, m (r – 1) is negative i.e. B in a diamagnetic material is less than that of vacuum. ...
