What magnification is used to inspect wires with a microscope?

• A. 6X
• B. 7X
• C. 8X
• D. 10X

Answer: (B)

Sevenfold magnification provides the right balance between seeing small defects and keeping enough field of view to assess the overall condition of a wire segment. It’s high enough to reveal hairline cracks in insulation, nicks, fraying, or tiny corrosion at terminations, yet not so high that you lose sight of the length and routing of the wire or struggle with a shallow depth of field. If you used a lower magnification, subtle flaws could be missed; if you used a higher magnification, the view becomes too narrow and makes it harder to judge damage patterns along the length of the wire. So, sevenfold is the practical compromise commonly used for inspecting wires with a microscope.
