The strong-force is responsible for holding the nuclei of atoms together. It is strong because it needs to overcome the mutual repulsion of the positive electric-charged protons in the nucleus, which would otherwise fly apart. However, the strong-force only has a very short range, and reaches only acrosss only about a femtometres.
For some decades the old simple description of the strong-force has been superceeded by the more modern quantum-chromodynamics, which involved the exotically named quarks and gluons.
The other fundamental forces (or fields) are the weak-force, the electro-magnetic-field, and gravity. The electro-magnetic-field is often referered to in termms of its electric-field and magnetic-field components.
