Question 145Electricity & Electronics - Assistant Engineer

The correct answer is A) Permeable iron. Permeable iron, also known as soft iron, is commonly used to shield sensitive electronic equipment from static magnetic fields. It has a high magnetic permeability, which allows it to effectively channel and contain magnetic fields, preventing them from interfering with the operation of the equipment. The other options, Bakelite, mica, and glass, are not effective at shielding against static magnetic fields. Bakelite and mica are non-magnetic materials, while glass is a poor conductor of magnetic fields and would not provide adequate shielding.
