Michael Faraday is credited with the discovery of electromagnetic induction on August 29, 1831. While Faraday receives credit for the discovery, electromagnetic induction may have been anticipated by the work of Italian priest and physicist Francesco Zantedeschi in 1829 or that of Joseph Henry, who around 1830 made a similar discovery, but did not publish his findings until later. Faraday formulated that electromotive force produced around a closed path is proportional to the rate of change of the magnetic flux through any surface bounded by that path.
It should take 20 to 30 minutes per pound of chicken at 300 to 350 degrees Fahrenheit. That works out to about two hours for a 4-pound chicken.
Chicken liver can simmer for 10 to 15 minutes after being added to boiling water. Chicken hearts can boil in lightly salted water for an hour. It will take about 90 minutes to cook beef hearts in lightly salted water; the water needs to be changed every 30 minutes during cooking.
