Magnetic shielding is done by surrounding the instrument to be protected from magnetic field by

Options

  1. Asoft ferromagnetic substance soft iron.
  2. Bdiamagnetic substance fine copper gauge.
  3. Cparamagnetic substance aluminum.
  4. Dparamagnetic material tantalum.

Correct answer

A. soft ferromagnetic substance soft iron.

Step-by-step solution

Magnetic shielding employs a surrounding layer of soft ferromagnetic substance like soft iron. Due to its high magnetic permeability, the external magnetic field lines are diverted or absorbed, reducing their impact on the protected instrument.
