Correct answer
Explanation
A horseshoe magnet is bent into a U-shape, which brings both poles closer together to create a stronger magnetic field in the space between them. This design is commonly used in educational demonstrations and for lifting small metal objects. Bar magnets are straight, cylindrical magnets are round, and magnetic needles are thin compass-style magnets.
