For protecting sensitive equipment from an external magnetic field, which among the following is the most effective solution?

Options

  1. AWrap insulation around it
  2. BPlace inside an iron can
  3. CSurround with fine copper sheet
  4. DPlace inside an aluminum can

Correct answer

B. Place inside an iron can

Step-by-step solution

The iron can produce a magnetic screening for the equipment as most of the magnetic lines of force will flow through iron and very less number of lines will be present in the space around the equipment.
