The statement "friction force is a contact force while magnetic force is a non-contact force" is always true.

Friction force is a type of force that occurs when two objects come in contact and rub against each other. It is caused by the microscopic irregularities on the surfaces of the objects, which create resistance when they slide past each other. Friction force is always a contact force because it requires direct physical contact between the objects. For example, when we walk, the friction between our feet and the ground allows us to move forward.

On the other hand, magnetic force is a force that acts between magnets or between a magnet and certain materials, such as iron. Unlike friction force, magnetic force does not require direct physical contact between objects. It can act through a medium, such as air or water. This is why we can feel the force between magnets even when they are not touching each other.

Therefore, option 1 is the correct answer because the statement holds true regardless of the temperature or any other external factors.
