Paul sprinkles iron filings onto a piece of paper near a bar magnet. The iron filings quickly become arranged in a pattern all around the bar magnet. Which argument does this evidence BEST support?

Question

a
Larger magnets can attract more objects.
b
Magnetic fields exist between objects that are not in contact with each other.
c
A magnet can attract magnetic objects through various materials.
d
Only objects that are made of metal have a magnetic field.

Answer 1

The evidence provided by Paul sprinkling iron filings around a bar magnet best supports the argument:

b. Magnetic fields exist between objects that are not in contact with each other.

The arrangement of the iron filings demonstrates the presence of a magnetic field created by the bar magnet, which can influence the filings even though they are not physically touching the magnet.
