Which of these materials requires the least value of magnetic field strength to magnetize it?

Options

  1. ANickel
  2. BSilver
  3. CTungsten
  4. DSodium Chloride

Correct answer

A. Nickel

Step-by-step solution

The least value of magnetic field strength required to magnetize is nickel because it is a ferromagnetic material. Ni is a ferromagnetic substance which gets strongly magnetized when placed in an external magnetic field. When external magnetic field B 0 , is applied the magnetic domains orient themselves in the direction of magnetic filed and grow in size. Hence, Ni requires least value of magnetic strength. NaCl is a diamagnetic material. Its field lines are repelled.
