Electricity is a form of energy that is transmitted through the wires especially copper wires for operating the various machines and devices such as lights, fans, refrigerator, computers, television, air conditioner, washing machines, etc. Electricity is the property of charged particles such as electrons and protons. When these particles are at rest, it is called static electricity. Static electricity occurs due to the existence of charged particles. On the other hand, when charged particles flow through the conductor, it is called current electricity. Because, when the charged particles flow through the conductor, electricity also flows.

This activity went along well with the second part of this unit, magnetism. For it, the class began by looking at various different materials and then held a cow magnet up to them to see if they were magnetic or not. It resulted in showing that only the paper clip and the nail were magnetic. The next section focused on where on the magnets the attraction was the strongest. To find this, the class took the cow magnets and held them to enclosed iron fillings. The fillings pooled around the two poles of the magnets.

Electromagnetism

Optics Diffraction: Topic Page Bending of waves around the edge of an obstacle. When light strikes an opaque body, for instance, a shadow forms on the side of the body that is shielded from the light source. Ordinarily light travels in straight lines through a uniform, transparent medium, but those light waves that just pass the edges of the opaque body are bent, or deflected.

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. A magnetic 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.

  1. It's helpful to know that magnetism works similarly to electric fields and gravity. I now sometimes think of gravity as just a giant magnetic and it.

  2. UNIT OVERVIEW We use electricity and magnetism every day, but how do they electrons produce a magnetic field, and spinning magnets cause an electric.

  3. Electricity and magnetism are manifestations of a single underlying electromagnetic force. Electromagnetism is a branch of physical science that describes the.
