Which statement about magnetic forces is true?

• A. Magnetic forces are only effective at short distances
• B. Magnets attract only metallic objects
• C. Magnetic force can act at a distance
• D. Magnetic forces require physical contact to work

Answer: (C)

Magnetic force can indeed act at a distance. This phenomenon is one of the key characteristics of magnetism; magnets can exert attractive or repulsive forces on other magnets or magnetic materials without any physical contact. This is primarily due to the magnetic field produced by magnets, which extends around them and influences other magnetic objects within that field. The ability for magnetic forces to operate over a distance allows for various applications, including the functioning of magnetic levitation, electric motors, and magnetic separation techniques. Understanding that magnetic force operates remotely highlights the broader principles of non-contact forces in physics.
