If a crack exists in a circular magnet, the attraction of magnetic particles to the crack is caused by a:

A circular field may be induced into a specimen by:

Fluorescent magnetic particle indications should be inspected under:

Using the residual test method, a number of parts are magnetized and laid on a rack prior to application of magnetic particles. Why is it important that they do not rub or touch each other?

Magnetic particle inspection is a reliable method for detecting all of the following indications except:

To detect lengthwise defects on the inside diameter of a hollow part, you should:

Which of the following is most often used for dry magnetic particle inspection?

Why should parts be cleaned after demagnetization?

Which form of magnetization is easiest to control in most parts?

When preparing a bath, it is important to have the bath strength at a proper level because too many particles can result in:

Longitudinal magnetization can be established in an article by:

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:

A discontinuity lying open to the surface is usually more harmful to an article than a discontinuity lying below the surface

With the dry continuous method, the powder particles are applied at which of the following times?

The most frequent cause for non-relevant indications is:

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

In what way should dry magnetic particles be applied to a magnetized area?

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

If a current of the same amperage is passed through two conductors one of which is magnetic and the other nonmagnetic, the magnetic conductor will have a stronger field within it than will the nonmagnetic conductor.

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