An experiment on the magnetic hysteresis and remanence of Rajmahal basalts

  • A. K. Rakshit
  • S. K. Dutt


Hysteresis curves of Rajmahal Trap basalts in Bihar are drawn and their coercivities obtained. The experimental arrangements and the procedure are described. The initial remanent magnetisation curves of the specimens are also drawn with the help of the same arrangement. Coercive forces of the rock specimens tested range from 70 to 237 oersteds. The values of saturation magnetisation and remanent magnetisation of two typical specimens are also given.
