Course Description

There are many factors that are considered when selecting the type of current and calculating the amperage required to magnetize a part. Understanding these calculations is important knowledge for the NDE technician.

By the end of this course, you will be able to

• List factors that affect the required amperage to magnetize a part

• Identify parts and coils that are classified as low, intermediate, and high fill factors

• Identify parts and central conductors that are classified as low, intermediate, and high fill factors

• Calculate amperage required for a head shot

• Calculate amperage required for a coil shot

• Calculate amperage required for a central conductor

• Identify the effective magnetized region of a part in a coil

• Identify the effective magnetized region of a part centered on a central conductor

• Identify the effective magnetized region of a part offset on a central conductor

Estimated completion time (hours): 1.6
