Maximum ferromagnetism is found in?
  • ✓
    $Fe$
  • B
    $Ni$
  • C
    $Co$
  • D
    None
✓

Answer

Correct option: A.
$Fe$
As Iron have highest value of saturation, Magnetization $M_s$​ which is defined as the magnetic moment density when the material is subjected to a field strong enough to align all its moments.
$\ce{Fe 1707 M_s}$
$\ce{Co 1400 M_s}$​
$\ce{Ni 485 M_s}$
