Question

1. which of the following best explains why a magnet can make a paperclip move without touching it? the magnet applies a normal force to the paperclip. a magnetic force is acting at a distance. gravity is pulling the paperclip toward the air. friction is pulling the paperclip toward the magnet.

Explanation:

Magnetic force is a non - contact force. A magnet can attract a paperclip from a distance because magnetic fields can act over space. Gravity acts vertically downward and is not responsible for the paperclip moving towards the magnet. Friction is a contact force and not relevant here. Normal force is a contact force perpendicular to the surface of contact and also not applicable.

Answer:

B. A magnetic force is acting at a distance
