Non-contact forces are forces that act between two objects that are not physically touching each other. Examples of non-contact forces include:
A magnetic force is experienced by any magnetic material in a magnetic field.
Opposite magnetic poles (N–S or S–N) attract each other. Like magnetic poles (N–N or S–S) repel each other:
A gravitational force is experienced by any mass in a gravitational field.
Masses are attracted towards each other by gravitational force:
