Magnetic Particle Inspection and Electromagnetism Flashcards

Flashcards related to Magnetic Particle Inspection and Electromagnetism, covering key terms, definitions, and principles discussed in the lecture notes.

Magnetic Particle Inspection

A method used on ferrous materials where magnetization reveals surface or near-surface discontinuities.

Electromotive Force

The force that causes electrons to move through a conductor.

Electric Current

The movement of electrons along a conductor, resulting directly from electromotive force. It flows from the negative to the positive terminal.

Ampere (Amps)

The unit of measure for electric current, representing the rate at which electrons pass a given point in a conductor.

Magnetic Lines of Force

Aligned at right angles (90°) to the direction of electric current flow; the direction can be controlled by controlling the electric current.

Magnetic Permeability

The ease with which a ferromagnetic part is magnetized by a magnetic field.

Retentivity

The ability of a material to remain magnetized after the magnetizing force is removed.
