ELECTROMAGNETIC CHARGE
TRY SOME QUICK QUESTIONS AND ANSWERS TO GET STARTED
There are two types of electric charge, positive (+) and negative (-).
Opposite charges attract: Charges with opposite signs (positive and negative) attract each other.
Like charges repel: Charges with the same sign (both positive or both negative) repel each other.
About the diagram
About electric charge
The electromagnetic force is produced by positive and negative electrical charges and manifests as electromagnetic fields, which include both electric and magnetic components.
- From a classical perspective, electromagnetic fields are represented as electromagnetic waves with continuous and smooth oscillations in wavelength and frequency.
- Quantum physics describes electromagnetic fields as being composed of photons, which are discrete and quantized packets of energy and momentum.
- In quantum physics, quantization refers to the concept that certain physical properties, such as energy, charge, and angular momentum, are not continuous but exist in discrete units called quanta.
- Quanta represent the smallest possible, indivisible amounts of physical properties, which fundamentally changes our understanding of interactions at the microscopic scale.
