Magswitch Mag Yoke Crack Tester - 8100551

• Permanent magnet (DC) yoke used to generate static fields for magnetic particle inspections on ferromagnetic materials.
• Span the MagYoke across suspect joints in ferromagnetic materials and rotate the knob clockwise to turn on a powerful DC magnetic circuit through the workpiece.
• A constant magnetic flux will flow from foot to foot, concentrating at flaws in materials or joints, resulting in stronger magnetic fields above incomplete joints, gaps or cracks in the material, and porous regions.
• Magnetic powders or fluids will accumulate around these defects due to the increased magnetic flux concentration and leakage.
• Note that surface magnetic field strength decreases on thicker materials, which makes detection more difficult unless more precise detection methods are used.
• Although the MagYoke does feature strong breakaway forces on most material thicknesses, it should not hold work in place while welding.
• We recommend BoomerAngles, Magsquares, or similar tools for fixturing needs.
