Libby is doing experiments with two different magnets. Magnet A can only attract thumbtacks that are up to 1 inch away from it. Magnet B can attract thumbtacks that are up to 3 inches away from it.

Question

What is likely true of the magnets?
A.
Magnet B is stronger than magnet A.
B.
Magnet A is stronger than magnet B.
C.
Magnet B is rectangular, and magnet A is shaped like a horseshoe.
D.
Magnet A is rectangular, and magnet B is shaped like a horseshoe.

Answer 1

Based on the information provided about the attraction distances of the two magnets, the likely conclusion is:

A. Magnet B is stronger than magnet A.

This is because Magnet B can attract thumbtacks from a distance of up to 3 inches, which is greater than the 1 inch distance of Magnet A. Therefore, it suggests that Magnet B has a stronger magnetic field or greater strength in attracting the thumbtacks within that range. The other options regarding the shapes of the magnets do not have enough evidence to be considered true based on the information given.
