Magnetic materials behave very differently when placed in a magnetic field. Some are weakly attracted, some are strongly attracted, and some are actually repelled. Understanding paramagnetic, diamagnetic, and ferromagnetic substances is an important concept for exams.
Every material contains electrons, and electrons behave like tiny magnets due to their spin.

| Type | Behavior in Magnetic Field | Strength |
|---|---|---|
| Diamagnetic | Repelled | Very Weak |
| Paramagnetic | Weakly attracted | Weak |
| Ferromagnetic | Strongly attracted | Very Strong |
Diamagnetic materials are repelled by a magnetic field.
All electrons are paired, so their magnetic effects cancel each other.
| Property | Diamagnetic |
|---|---|
| Electron pairing | All paired |
| Magnetic behavior | Repelled |
| Strength | Very weak |
Paramagnetic materials are weakly attracted to a magnetic field due to unpaired electrons.
| Property | Paramagnetic |
|---|---|
| Electron pairing | Some unpaired |
| Magnetic behavior | Weak attraction |
| Strength | Weak |
Ferromagnetic materials are strongly attracted to magnetic fields.
| Property | Ferromagnetic |
|---|---|
| Electron pairing | Many unpaired |
| Magnetic behavior | Strong attraction |
| Strength | Very strong |
| Property | Diamagnetic | Paramagnetic | Ferromagnetic |
|---|---|---|---|
| Attraction | Repelled | Weakly attracted | Strongly attracted |
| Electrons | All paired | Some unpaired | Many unpaired |
| Strength | Very weak | Weak | Very strong |
| Permanent magnet | No | No | Yes |
| Material | Value |
|---|---|
| Diamagnetic | Negative |
| Paramagnetic | Positive (small) |
| Ferromagnetic | Positive (large) |
| Type | Application |
|---|---|
| Diamagnetic | Magnetic levitation |
| Paramagnetic | MRI, chemistry |
| Ferromagnetic | Motors, transformers |
| Mistake | Correct Concept |
|---|---|
| All metals are magnetic | Only iron, cobalt, nickel are strongly magnetic |
| Paramagnetic = strong | Paramagnetic = weak |
| Diamagnetic = no effect | Diamagnetic = repelled |
