Jim drops an iron magnet during a chemistry lab experiment. She finds that it is no longer magnetic. What has happened in terms of its properties?

AA chemical change occurred that changed the iron in the magnet into nickel.
BA physical change occurred that changed the iron in the magnet into nickel.
CA chemical change occurred in which the iron remained iron, but lost one of its chemical properties.
DA physical change occurred in which the iron remained iron, but lost one of its physical properties.

I think the correct answer from the choices listed above is option D. A physical change occurred in which the iron remained iron, but lost one of its physical properties. Its magnetic property is lost due to some factors. Hope this answers the question. Have a nice day.

Answer:

d. A physical change occurred in which the iron remained iron, but lost one of its physical properties.

Explanation:

Iron is magnetic because domains can be arranged in single direction in presence of external magnetic field. It can be de-magnetized by heating, hammering and other methods.

When a iron is dropped in the lap, the domains get randomly aligned and it loses its magnetism. Magnetism is a physical property. There is no change in the chemical property.
