Distinction between diamagnetic, paramagnetic and ferromagnetic substances
|
Property |
Diamagnetic |
Paramagnetic |
| (i) |
Susceptibility (x) |
-1 ≤ x < 0 (negative and small) |
0 < x < ε (positive and small) |
| (ii) |
Permeability (μr) |
0 ≤ μr <1(less than 1) |
1 < μr < 1 + ε (slightly greater than 1) |
| (iii) |
Coercivity Example |
High Gold |
Low Platinum |
