Question

if a magnetized object is struck, the vibration often causes the molecules to rearrange themselves in a _________ fashion.
a. ordered
b. positive
c. negative
d. disordered

Explanation:

Analyze the physical process of striking a magnet

Using the Magnetic Domains knowledge point
Striking or vibrating a magnetized material imparts kinetic energy to its atoms. This thermal or mechanical agitation disrupts the aligned magnetic dipoles (domains) that produce the external magnetic field.

Determine the resulting arrangement

Using the Magnetic Domains knowledge point
The mechanical shock overcomes the magnetic forces holding the domains in alignment, causing them to point in random directions. This random realignment is described as a disordered fashion, which demagnetizes the object.

Answer:

• a. ordered
• b. positive
• c. negative
• d. disordered (Correct answer)
