In electrical engineering, electromagnetic shielding is the practice of reducing or redirecting the electromagnetic field (EMF) in a space with barriers made of conductive or magnetic materials. It is typically applied to enclosures, for isolating electrical devices from their surroundings, and to cables to isolate wires from the environment ...
In 1754, Jean-Antoine Nollet published an account of the cage effect in his Leçons de physique expérimentale. [2] In 1755, Benjamin Franklin observed the effect by lowering an uncharged cork ball suspended on a silk thread through an opening in an electrically charged metal can. The behavior is that of a Faraday cage or shield.
An EMP such as a lightning strike can physically damage objects such as buildings and aircraft. The management of EMP effects is a branch of electromagnetic compatibility (EMC) engineering. The first recorded damage from an electromagnetic pulse came with the solar storm of August 1859, or the Carrington Event. [2]
A variant of this is the high altitude EMP (HEMP) nuclear weapon, designed to create the pulse as its primary destructive effect. Non-nuclear electromagnetic pulse (NNEMP) weapons. Sources of repetitive EMP events, sometimes as regular pulse trains, include: Electric motors; Electrical ignition systems, such as in gasoline engines.
Fear not — Edmunds explains what electric car batteries are made of. To start, let's establish that even though a Tesla battery and a Chevrolet Bolt battery are both lithium-ion batteries, that ...
A solid-state electrolyte (SSE) is a solid ionic conductor and electron-insulating material and it is the characteristic component of the solid-state battery. It is useful for applications in electrical energy storage in substitution of the liquid electrolytes found in particular in the lithium-ion battery .
