A non-contact force is a force applied to an object by another body that is not in direct contact with it. The most familiar example of a non-contact force is weight. In contrast a contact force is a force applied to a body by another body that is in contact with it.
a contact force, is a force that acts at the point of contact between two objects in contrast to body forces. Contact forces are described by Newton's laws of motion, as with all other forces in dynamics.

Answer:
Contact & Non-contact forces
External force comes into picture when the body starts moving or comes to rest either by coming in contact with the body or without being in contact.
Contact force-
force applied by coming in contact with the body
Example:
- hitting of cricket ball with bat in game
Non-contact force-
force applied without coming in contact with body.
Example:
- coin attracted towards magnet(magnetic force)
- ball dropped at height attracted towards the earth (gravitational force)
