A student uses a magnet to place a picture on the refrigerator door. Which statement explains how the man is able to stick to the refrigerator without directly touching it.A. The force of gravity between the refrigerator and the magnet is strong enough to cause the magnet to stick.B. The pictures on magnetic field attracts both a magnet and the refrigerator. C. The magnets magnetic field. Can act at a distance and influence the middle of the door through the picture d. Friction acts through the picture and allows the magnet to stick to the refrigerator.
C. The magnet's magnetic field can act at a distance and influence the metal of the door through the picture.
Magnetic fields are invisible force fields that can exert a force on materials that are susceptible to magnetism, such as iron or steel, without needing direct contact. The refrigerator door is typically made of a metal that can be influenced by a magnet. When the student places the magnet near the door, the magnetic field of the magnet interacts with the metal in the door, causing an attractive force that holds the magnet (and the picture attached to it) in place against the door. This is why the magnet can stick to the refrigerator door even through the picture.
