My mom had some chest pain and a cough in the middle of the night, so she went to the 24 hr center at city of hope. They drained her lungs and sent her home after she seemed to be ok. She's been home with no new issues. Then I get an email from the doctor that the fluid came back positive for cancer.
Electromagnetic induction is the production of an electromotive force across a conductor exposed to time varying magnetic fields. Michael Faraday, who mathematically described Faraday's law of induction, is generally credited with its discovery in 1831.hen the coils are stationary, no current is induced. But when the small coil is moved in or out of the large coil (B) , the magnetic flux through the large coil changes, inducing a current which is detected by the galvanometer (G) .
William Gilbert first coined the term âelectricityâ from the Greek word for amber. Gilbert wrote about the electrification of many substances in his âDe magnete, magneticisique corporibusâ. He was also the first person to use the terms electric force, magnetic pole, and electric attraction.ncient Egyptian texts dating from 2750 BC referred to these fish as the âThunderer of the Nileâ, and described them as the âprotectorsâ of all other fish. They were again reported millennia later by ancient Greek, Roman and Arabic naturalists and physicians.
