Electromagnetic radiation is energy that travels through space in the form of waves, such as light, radio waves, and X-rays.
What is the electromagnetic force?
The electromagnetic force is one of the four fundamental forces of nature, responsible for interactions between charged particles.
What is the Poynting vector?
The Poynting vector represents the directional energy flux or power flow of an electromagnetic field.
How is electromagnetic energy conserved?
Electromagnetic energy conservation is described by the Poynting theorem, which states that the rate of energy transfer is equal to the sum of the electromagnetic energy entering a region minus the energy dissipated as heat.
What is wave-particle duality?
Wave-particle duality is the concept that every particle or quantum entity exhibits both wave-like and particle-like properties.
What is an eddy current?
Eddy currents are loops of electric current induced within conductors by a changing magnetic field, and can cause energy losses in magnetic cores.
What are the applications of electromagnetic fields in medicine?
Applications include diagnostic techniques like MRI, cancer treatments with radiotherapy, and wound healing with electromagnetic therapy.
What is electromagnetic compatibility (EMC)?
EMC is the ability of electrical equipment to operate without interfering with other devices, essential for preventing malfunctions.
What is synchrotron radiation?
Synchrotron radiation is high-energy electromagnetic radiation emitted by charged particles accelerated at speeds close to the speed of light through magnetic fields.
What is the role of electromagnetic waves in climate science?
Electromagnetic waves are used in climate science for remote sensing of weather patterns, solar radiation monitoring, and understanding atmospheric conditions.
What is a cyclotron?
A cyclotron is a type of particle accelerator that uses electromagnetic fields to propel charged particles to high speeds in a spiral path.
What is plasma and how is it related to electromagnetism?
Plasma is an ionized state of matter composed of free electrons and ions, and its behavior is dominated by electromagnetic forces.
What technique uses electromagnetic fields to accelerate particles?
Particle accelerators use electromagnetic fields to accelerate and collide particles for experiments in particle physics.
What is quantum electrodynamics (QED)?
QED is the quantum field theory of the electromagnetic force, describing how light and matter interact.
How do electromagnetic waves propagate in different media?
Electromagnetic waves propagate through different media by reflecting, refracting, absorbing, or transmitting depending on the medium's properties.
