Examples of Non-Contact Forces are :
Gravitational force.
Magnetic force.
Gravity : Gravitation or Gravity is a process by which bodies with a physical weight, however, small it is, are attracted towards earth surface. They are attracted by a force which is proportional to their weight.Gravitation is responsible for keeping all the planets in their respective orbit around the sun and is the non contact force at its best.
The Universal law of gravitation can be stated as:
"Every particle in the universe attracts every other particle with a force that is directly proportional to the product of their masses and inversely proportional to the Square of the distance between them".Mathematically, it can be stated as:

m1 = mass of object 1
m2 = mass of object 2
The direction of force is from the body acted upon towards the body applying it. The weight of the human body is also a non contact force exerted by earth on human.
MAGNETISM : It is a property by virtue of which certain special substances called 'magnets'� exert a special force on other magnets or substances made up of iron. This force is called magnetic force which is a kind of non contact force as the materials just need to be in the vicinity of the magnet.
This is non contact because there is no physical contact between the materials. This force is due to the magnetic field developed around the magnet. These magnets have two poles called South andNorth. Like poles repel each other while unlike poles attract each other.Magnetic fields are non contact forces as they push or pull objects without touching them. They exhibit these properties just on a few magnetic materials not on all Depicting Magnetism
There are many kinds of magnetism like:
DiamagnetismFerromagnetismParamagnetismAntiferromagnetismElectromagnetism
