Describing a substance or object that lacks the properties of a magnet; specifically, it does not exhibit magnetic attraction or repulsion. This state results from the random orientation of the magnetic domains within the material, negating any overall magnetic field. The object may be composed of ferromagnetic material but has not been subjected to a magnetizing influence, or it has been demagnetized after being previously magnetized. It can be induced into a magnetic state, making it temporarily 'magnetizable'.
Unmagnetized meaning with examples
- The iron filings, scattered on the table, remained motionless near the unmagnetized steel bar. It showed no attraction, demonstrating its lack of magnetic properties, unlike a bar magnet which would immediately draw them in. Thus, the bar was deemed unmagnetized before the experiment. This shows a control for the experiment.
- During the manufacturing process, the steel components were cooled in a manner that left them unmagnetized. This step ensured that the parts could be handled and assembled without any unwanted magnetic interactions, such as sticking to tools. This allows the metal to be easily worked with, as any magnetism would hinder production.
- After the car's engine had been serviced, the mechanic confirmed that the spark plugs were unmagnetized to avoid issues with the fuel injection system. This would ensure that the car started reliably and would be easier to maintain. It also eliminated any potential interference during operation of the vehicle. This is a vital safety step.
- The scientist discovered a specific heating process that consistently rendered the samples of nickel unmagnetized. This was a key step in their research as it established a baseline against which they could measure the effects of various magnetic treatments. This allows the scientist to make precise comparisons of materials.
