Homing of Magnetized and Demagnetized Pigeons [PDF]
Journal of Experimental Biology, 1988 ABSTRACT Homing pigeons appear to use the earth’s magnetic field as a compass and perhaps as part of their position-finding system or ‘map’. The sensory system they use to detect magnetic fields is unknown, but two current possibilities are some mode of response by the pineal organ or by the visual system, or it may be based on the ...

Fast Demagnetization and Vibration Reduction in Switched Reluctance Motor Drive System
IEEE Access, 2021 In this paper, a Switched Reluctance Motor (SRM) drive system is proposed to make a trade-off between torque profile and vibration amplitude. In the proposed drive system, the power factor correction and fast demagnetization are achieved using a single ...

Geophysical Research Letters, 1981 The effects of pressure on the ramanent magnetization of rocks may well be important in regions of low geothermal gradients, for example subduction zones, or at localities where a magnetization is associated with a meteorite impact. In a series of experiments undertaken to determine the effects of hydrostatic pressure on the saturation magnetic ...
