The link between electricity and magnetism

Subcategories

• Electromagnetic analysis - the process of analyzing and interpreting electromagnetics
• Electromagnetic compatibility - the study of unintentional generation, propagation and reception of electromagnetic energy
• Electromagnetic coupling - also known as radiative coupling, the phenomena of when the source of unwanted electromagnetic generation is a great distance away from its unintended receiver
• Electromagnetic devices - various devices which use electromagnetic components, such as speakers, tape heads, electric motors, etc
• Electromagnetic fields - the field produced by moving electrically charged objects
• Electromagnetic induction - the process of generating an electric current via moving a conductor through a magnetic field
• Electromagnetic radiation - a form of energy which has both electric and magnetic field components and behaves like a waveform when travelling through space
• Electromagnetic shielding - the process of reducing the electromagnetic field in a certain space by the use of conductors or magnets
• Electromagnetic transients - a method of exploration measuring the decay of electric and magnetic fields which are induced by transient pulses of electric current
• Proximity effect - the effect which describes the current crowding that occurs when currents flow through one or more nearby conductors
