The strong force is ‘carried’ by particles called gluons that is, when two particles interact through the strong force, they do so by exchanging gluons. It is basically attractive but can be effectively repulsive in some circumstances. It is responsible for holding the nuclei of atoms together. The strong interaction is very strong but very short-ranged. Electricity, magnetism, and light are all produced by this force. It can be attractive or repulsive and acts only between pieces of matter carrying an electrical charge. It is long-ranged but much weaker than the strong force. The electromagnetic force causes electric and magnetic effects such as the repulsion between like electrical charges or the interaction of bar magnets. the conversion of a neutron into a proton, an electron and an antineutrino. The weak force is responsible for radioactive decay and neutrino interactions. It acts between any two pieces of matter in the Universe since mass is its source. The gravitational force is weak but very long-ranged. Strong Nuclear Force – Strongest but short range.Electromagnetic Force – Stronger, with infinite range.Weak Nuclear Force – Next weakest but short range.Gravitational Force – Weakest force but has infinite range.
