MHT CET · Physics · Magnetic Properties of Matter
Magnetic shielding is done by surrounding the instrument to be protected from magnetic field by
- A soft ferromagnetic substance soft iron.
- B diamagnetic substance fine copper gauge.
- C paramagnetic substance aluminum.
- D paramagnetic material tantalum.
Answer & Solution
Correct Answer
(A) soft ferromagnetic substance soft iron.
Step-by-step Solution
Detailed explanation
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.
