Description

AC in magnetic particle inspection is effective only for the detection of _____________ discontinuities. These types of discontinuities comprise the majority of service-induced defects.
The shallow penetration of AC fields into the part at the usual power line frequencies of 50 and 60 hertz hinders the use of AC for the detection of subsurface discontinuities. This shallow penetration is due to a __________ effect.
Dry powder particles in the presence of AC or HWDC fields have mobility on a surface due to the _________________ character of the fields.
The “__________________” of the powder helps it to move to the area of leakage fields and to form stronger indications. This effect is less pronounced in the wet technique
Low ___________________ is important because the particles themselves never become strongly magnetized so they do not stick to each other or the surface of the part.
Magnetic particles are also supplied in a wet suspension such as water or oil. The wet magnetic particle testing method is generally more sensitive than the dry because the __________________ provides the particles with more mobility and makes it possible for smaller particles to be used since dust and adherence to surface contamination is reduced or eliminated.
The ultimate in visibility and contrast is achieved by coating the magnetic particles with a _________________ pigment (usually available in wet method materials only).
Any ferromagnetic material subjected to magnetic particle inspection requires ______________________.
A ________________ field can impede the operation of some parts, as well as, affect the operation of adjacent equipment sensitive to low level stray magnetic fields.
___________________ Is the opposition that a ferromagnetic material shows to the establishment of a magnetic field. Reluctance is analogous to the resistance in an electrical circuit
___________________ is the ability of some chemical compounds to emit visible light when exposed to near ultraviolet radiation.
A _________________ is an instrument that translates light energy into an electrical current.

Frequently Asked Questions

What is a crossword?

Crossword puzzles have been published in newspapers and other publications since 1873. They consist of a grid of squares where the player aims to write words both horizontally and vertically.

Next to the crossword will be a series of questions or clues, which relate to the various rows or lines of boxes in the crossword. The player reads the question or clue, and tries to find a word that answers the question in the same amount of letters as there are boxes in the related crossword row or line.

Some of the words will share letters, so will need to match up with each other. The words can vary in length and complexity, as can the clues.

Who is a crossword suitable for?

The fantastic thing about crosswords is, they are completely flexible for whatever age or reading level you need. You can use many words to create a complex crossword for adults, or just a couple of words for younger children.

Crosswords can use any word you like, big or small, so there are literally countless combinations that you can create for templates. It is easy to customise the template to the age or learning level of your students.

Are crosswords good for students?

Crosswords are a great exercise for students' problem solving and cognitive abilities. Not only do they need to solve a clue and think of the correct answer, but they also have to consider all of the other words in the crossword to make sure the words fit together.

Crosswords are great for building and using vocabulary.
