True. Magnetic forces can repel objects without them physically touching because the magnetic fields generated by the objects interact to create a repelling force.
False. Magnetic interactions can occur even when the interacting objects are not touching. Magnetic fields can exert forces on objects at a distance, such as between a magnet and a piece of metal.
Gravity, electrical force, magnetic force. These can act with direct touch. "False" forces which are dependent on the observer's motion, such as centrifugal force and g forces are also sometimes considered as non-contact There are also some nuclear forces, but they are not normally observed, and electrical and magnetic forces are really two sides of the same coin.
False. Magnetism is not a contact force. It can act at a distance, meaning magnets can exert forces on each other without physical contact. This is due to their magnetic fields interacting with each other.
False. Magnetic force and gravitational force are two distinct types of forces. Gravitational force is the force of attraction between objects due to their mass, while magnetic force is the force between magnets or between a magnet and a magnetic material.
False. Magnetic poles and domains are different concepts. Magnetic poles refer to the regions of a magnet where the magnetic force is concentrated, while domains are regions within a magnetic material where the magnetic moments of atoms are aligned in the same direction.

It is true that materials that exert magnetic forces are considered magnets. This is the case since it shows they have magnetic field lines that may have been induced or were naturally present in the materials.
False. Magnetic poles and domains are different concepts. Magnetic poles refer to the regions of a magnet where the magnetic force is concentrated, while domains are regions within a magnetic material where the magnetic moments of atoms are aligned in the same direction.
When two objects are touching each other, the net force between them is zero if they are at rest or moving at a constant velocity. The forces between the objects are balanced, leading to no acceleration.
False. Forces can also set stationary objects in motion.
False. Electric forces are caused by the interaction of charged particles (like electrons and protons), but friction and contact forces are primarily a result of mechanical interactions between objects.
