Description
ELECTROMAGNETIC CHARGE
TRY SOME QUICK QUESTIONS AND ANSWERS TO GET STARTED
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.
Protons: Carry a positive charge. Electrons: Carry a negative charge. Quarks: Fundamental particles that carry fractional charges.
There are two types of electric charge, positive (+) and negative (-).
Electromagnetic charge is a fundamental property of matter that determines how a particle interacts with the electromagnetic field.Charges are either positive (+) or negative (-).
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.
