We use electromagnetic induction in many ways in our daily lives, in most cases without realizing it. One recent invention is a flashlight that works without a battery. Further, in air travel safety, electromagnetic induction is used to prevent dangerous metallic objects (such as knives and guns) from being carried on the planes. (i) When was electromagnetic induction discovered? To which human quality do you attribute this discovery? Visualize the scenario prior to this discovery. (ii) How does a batteryless flashlight work? (iii) How are passengers screened at the airport?
