The diagram below shows a magnet and two paper clips.
Why was Paper Clip 2 attracted to Paper Clip 1 after Paper Clip 1 was stuck to the magnet?
a
The magnet repelled Paper Clip 2 and made it attach itself to Paper Clip 1.
b
Magnetism traveled through Paper Clip 1 to Paper Clip 2 and made them magnetic.
c
Magnetism was already present in Paper Clip 1 and Paper Clip 2 when they were attached to the magnet.
d
Attaching the magnet to Paper Clip 1 caused it to transform Paper Clip 2 into a new material that was magnetic.
c. Magnetism was already present in Paper Clip 1 and Paper Clip 2 when they were attached to the magnet. The magnet induces a magnetic field in Paper Clip 1, which then attracts Paper Clip 2 because of its own induced magnetic field.
b
Magnetism traveled through Paper Clip 1 to Paper Clip 2 and made them magnetic.
The correct answer is b. Magnetism traveled through Paper Clip 1 to Paper Clip 2 and made them both magnetic.
When a magnet is brought close to a magnetic material like a paper clip, the magnet's magnetic field can induce magnetism in the material. This happens because the magnetic field of the magnet aligns the magnetic domains (tiny groups of atoms with aligned magnetic fields) within the material. In this case, when the magnet is brought close to Paper Clip 1, its magnetic field induces magnetism in Paper Clip 1, making it magnetic.
Once Paper Clip 1 becomes magnetic, it then creates its own magnetic field. This magnetic field can then induce magnetism in nearby magnetic materials, such as Paper Clip 2. As a result, Paper Clip 2 becomes attracted to Paper Clip 1 and attaches to it.
So, in this scenario, Paper Clip 2 is attracted to Paper Clip 1 because magnetism traveled through Paper Clip 1 to Paper Clip 2, making them both magnetic.
