Question
Two students are learning about magnets. They are exploring what happens when a barrier is placed between a magnet and magnetic objects.
A pile of twenty paper clips is placed on a wooden table top. One of the students holds a magnet underneath the table top, directly beneath the paper clips. The student then slides the magnet along the underside of the table top. The other student observes and records what happens to the paper clips.
The students’ notes are shown below.
What would MOST LIKELY occur if a table top with a thickness of one centimeter were used? (All other aspects of the experiment are kept exactly the same.)
Responses
A More than 10 paper clips would follow the magnet across the table top.More than 10 paper clips would follow the magnet across the table top.
B More than 20 paper clips would follow the magnet across the table top.More than 20 paper clips would follow the magnet across the table top.
C Approximately 3-5 paper clips would follow the magnet across the table top.Approximately 3-5 paper clips would follow the magnet across the table top.
D Fewer than 2 paper clips would follow the magnet across the table top.
