1. Never cross each other 2. Have the same strength 3. Seek to path of least resistance 4. Decrease in density with increasing distance from the poles |
|
|
Dry magnetic particles |
Cannot be reused |
|
|
A yoke establishes a magnetic field; |
Between the north pole and south pole of the yoke |
|
|
Magnetic particle inspection has several advantages over liquid penetrant inspection which includes: |
1. Components with thin coatings can be inspected without removing the coatings 2. Components can be inspected more rapidly |
|
|
The opposition that a ferromagnetic material shows to the establishment of a magnetic field is called: |
Reluctance |
|
|
Ferromagnetic materials are made up of small polarized regions known as: |
Domains |
|
|
Components generally must be demagnetized because residual magnetism can: |
1. Affect machining and welding processes 2. Interfere with nearby electronic components 3. Increase wear by attracting abrasive particles |
|
|
A volume of space where there's a change in magnetic energy is called: |
A magnetic field |
|
|
An object that has a magnetic pole on one end and a second equal but opposite magnetic pole on the other is called a: |
Dipole |
|
|
A property of a material that describes the ease with which a magnetic flux is established in a component is called: |
Permeability |
