Share:
- 1By grounding the component to a zero reference level chassis ground to drain the magnetic charge.
- 2By applying a permanent magnet of equal and opposite strength to neutralize the external field.
- 3By using a high-permeability material (like a ferrite or Mu-metal) to provide a low-reluctance path that diverts the magnetic flux around the protected space.✓
- 4By surrounding it with a high-reluctance material that blocks the entry of magnetic lines of force.
Correct answer
By using a high-permeability material (like a ferrite or Mu-metal) to provide a low-reluctance path that diverts the magnetic flux around the protected space.
