gravitational force
Without physical contact detecting the presence of objects is the purpose of proximity sensors. They work based on inductive, magnetic, photoelectric and capacitive properties of objects.
Because it's not necessary for objects to be in contact (touching) in order to feel the magnetic force between them.
A non-contact force is any force applied o an object by another body that is not in direct contact with it,while A contact force is a force applied to a body by another body that is in contact with it. however it is to be noted that the origin of all contact forces can be traced to non-contact force.
Magnets have a magnetic field about them. This field can act on objects without the magnet coming in contact with the object.
no gravitational force is a non contact... a simple proof to that is that the Earth's centre is attracting you towards itself without you being in contact with it... also Sun is able to attract the planets from such a large distance....
Non-contact. Gravity can effect objects separated by hundreds of millions of light years -- which is why our galaxy is moving towards the Sharpley Super-cluster.
The force exerted by 2 objects in contact is called contact force. The force exerted by 2 objects without any contact is called non contact force
gravitational forces are experience between to objects without any contact between them
induction
Without physical contact detecting the presence of objects is the purpose of proximity sensors. They work based on inductive, magnetic, photoelectric and capacitive properties of objects.
Telekinesis is the production of motion in objects (my mind or supernatural means) without physical contact or manipulation.
Because it's not necessary for objects to be in contact (touching) in order to feel the magnetic force between them.

convection and radiation heat transfer bot occur without either object being in direct contact with each other.
