Study Notes
Electromagnetism
- Electromagnetism is an interaction between particles with electric charge via electromagnetic fields.
- The electromagnetic force is one of the four fundamental forces of nature.
- It is the dominant force in the interactions of atoms and molecules.
Characteristics of Electromagnetic Forces
- Electromagnetic forces occur between any two charged particles.
- They cause an attraction between particles with opposite charges.
- They cause repulsion between particles with the same charge.
- Magnetism is an interaction that occurs exclusively between charged particles in relative motion.
Electromagnetic Fields
- Electromagnetic fields are created in the vicinity of charged particles.
- These fields can accelerate other charged particles via the Lorentz force.
Electromagnetic Force and Weak Force
- At high energy, the weak force and electromagnetic force are unified as a single electroweak force.
- The electromagnetic force is responsible for many phenomena in the natural world.
