Question

give a brief information on current electricity and magnetism

Answer 1

The Electricity and Magnetism unit explains electricity, from charged particles at the atomic level to the current that flows in homes and businesses. ... Flowing electrons produce a magnetic field, and spinning magnets cause an electric current to flow. Electromagnetism is the interaction of these two important forces.

Answer 2

Explanation:

Electricity and magnetism are manifestations of a single underlying electromagnetic force. Electromagnetism is a branch of physical science that describes the interactions of electricity and magnetism, both as separate phenomena and as a singular electromagnetic force.

Amagnetic field is created by a moving electric current and a magnetic field can induce movement of charges (electric current). The rules of electromagnetism also explain geomagnetic and electromagnetic phenomena by explaining how charged particles of atoms interact.Before the advent of technology, electromagnetism was perhaps most strongly experienced in the form of lightning , and electromagnetic radiation in the form of light. Ancient man kindled fires that he thought were kept alive in trees struck by lightning.

Magnetism has long been employed for navigation in the compass. In fact, it is known that Earth's magnetic poles have exchanged positions in the past.
