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