Electromagnetic Interaction
Key Stage 5
Meaning
The electromagnetic interaction is the mechanism by which all particles with charge affect one another.
About The Electromagnetic Interaction
- The electromagnetic interaction is one of the 4 fundamental interactions governing how subatomic particles affect one another.
- The electromagnetic interaction causes positively charged particles to repel one another, negatively charged particles to repel one another and opposite charges to attract one another.
- The electromagnetic interaction acts to repel protons from one another in the atomic nucleus.
- The electromagnetic interaction is mediated by photons.

| This graph shows the strength of the force between two protons in the nucleus. The electromagnetic interaction between like charges is repulsive with a range of 0 to ∞. The strength of the force reduces proportional to 1/r2 where r is the distance between the centre of the charge distribution of each particle. |
