Question

Question 7


The image above shows a magnetized object.

True
False
Question 8
A nail can be magnetized when it comes into contact with a permanent magnet because its domains become aligned.

True
False

Answer 1

I can't see the image you mention. Please upload it or describe how the magnetic domains (little arrows) are arranged.

Guidance meanwhile:
- If the picture shows the domains mostly aligned in one direction, then Question 7 = True (object is magnetized).
- If the picture shows domains pointing randomly, then Question 7 = False (not magnetized).

Question 8: True. A nail can be magnetized by contact with a permanent magnet because the magnetic domains in the nail become aligned (or partially aligned) so the nail acquires a net magnetic field.
