An article has been circularly magnetized and retains a circular residual field. To replace the circular field with a longitudinal field, we longitudinally magnetize the article with a field that is as great or greater than:

Whenever an article has been circularly magnetized, the first step in the demagnetization procedures is to establish:

Surface seams in rolled bars are best detected in magnetic particle testing with:

A test object 10 inches (25cm) long and 2 inches (5 cm) in diameter , longitudinally magnetized in a 5-turn coil, requires a magnetizing current of: (NI = 45 000 / (L/D))

The only test method to use on articles made of soft steel with low retentivity is the ___________________ method.

When defects have been removed from an article, or have been repaired, the next step is to _________________________ the article.

When two pieces of steel rub against each other and either or both are in a magnetized condition, an indication is sometimes formed when magnetic particles are applied. This type of indications is called:
