Physics Question on Magnetic properties of materials
The .examples of diamagnetic, paramagnetic and ferromagnetic materials are respectively:
A
copper, aluininium, iron
B
aluminium, copper, iron
C
copper, iron, aluminium
D
aluminium, iron, copper
Answer
copper, aluininium, iron
Explanation
Solution
Diamagnetic substances when placed in a magnetic field are feebly magnetised opposite to the direction of the magnetising field, to example copper. Paramagnetic substances when placed in a magnetic field are feebly magnetised in a direction of the magnetising field, example aluminium. Ferromagnetic substances when placed in a agnetic field are strongly magnetised in the direction of the magnetising field, example iron.
