Question

Two kinds of magnets are shown below.



Jackson wants to hang a small piece of paper on the metal door of his refrigerator. Which type of magnet would be best for Jackson to use, and why?
A.
Magnet 1 would work best because it has a continuous magnetic field.
B.
Magnet 2 would work best because it would attract the refrigerator with more force.
C.
Magnet 1 would work best because it would attract the refrigerator with more force.
D.
Magnet 2 would work best because it has a continuous magnetic field.

Answer 1

C. Magnet 1 would work best because it would attract the refrigerator with more force.

Explanation: Magnet 1 has its poles close together so the magnetic field is concentrated between them. That stronger, concentrated field produces a greater attractive force on the metal door, so it will hold the paper more securely.
