Torque On A Current Loop In A Uniform Magnetic Field
... • Only the forces F2 and F4 contribute to the torque about the axis of rotation O. The other two forces on the loop would not produce a rotation as these forces would be equal in magnitude and opposite in direction and would also pass through the axis of rotation O, making the torque arm 0 m. ...

the influence of the mechanical fatigue on the energy loss
... Most machine parts are subjected to variation in applied loads, causing fluctuation in stresses in the parts. If the fluctuating stresses are of sufficient magnitude, even though the maximum applied stress may be considerably less than the static strength of the material, failure may occur when the ...

Magnetism - Cabrillo College
... Since atoms contain moving electrons (charges), we expect them also to exert and feel magnetic forces. However, in most materials, the electrons in different atoms all “spin” in different directions, so the magnetic forces all balance out and the material is non-magnetic. In iron, however, the elect ...
