Diamagnetic Material The materials that allow flow of magnetic field through them are called as Magnetic Materials. In Diamagnetic material there is no magnetism in the absence of external magnetic field. (Shown in fig. 1) When magnetic field is applied dipoles are induced and they orient in a direction opposite to external magnetic field. (As […]


Conducting Material (Cu vs Al) •Electrically Conducting Material :- This materials carry current in an electrical machine. •Highly Conducting Material :- Copper, Aluminum, Gold, Silver. •Highly resistive material:- Alloys (heating elements)             Now,    R=Ro(1+αΔT) Where α= temperature coefficient of resistance ΔT= Change in temperature of per degree Celsius ΔT= Change in temperature of per degree […]
