  2. Cobalt
  3. Nickel
  4. All of these

Iron
B
Cobalt
C
Nickel
D
All of these
Solution
Verified by Toppr

The correct option is D All of these

Ferromagnetic materials exhibit a long-range ordering phenomenon at the atomic level which causes the unpaired electron spins to line up parallel with each other in a region called a domain. Within the domain, the magnetic field is intense, but in a bulk sample the material will usually be unmagnetized because the many domains will themselves be randomly oriented with respect to one another. Ferromagnets will tend to stay magnetized to some extent after being subjected to an external magnetic field. This tendency to "remember their magnetic history" is called hysteresis. Nickel, iron and cobalt are such materials.
