Adeyɛ a ɛne sɛ anyinam ahoɔden yɛ adwuma. Faraday mmara – Twi

Michael Faraday ne Joseph Henry na wohuu adeyɛ a ɛfa electromagnetic induction ho no, nea efii sɔhwɛ a edi kan a esi adeyɛ a ɛfa electromagnetic induction so dua no mu bae no, Faraday tintimii wɔ 1931 mu. Adeyɛ a ɛne sɛ electromagnetic induction no yɛ nea ɛma electromagnetic voltage a wɔde ma ne current a wɔde ma no pue wɔ circuit a magnetic flux a ɛsakra bere mu no twa mu. A simple experiment illustrating the phenomenon is shown in Figure 1. Yɛwɔ coil bi wɔ ne terminals a yɛde milliammeter bata ho a ɛyɛ closed circuit. Yɛde magnet bi ba baabi a ɛbɛn saa ɔmansin yi. Sɛ magnet no home a, ammeter no nkyerɛ sɛ anyinam ahoɔden biara. Sɛ magnet no kɔ anim ne akyi wɔ coil no dannan ntam a ammeter no needle no twe ne ho a ɛkyerɛ sɛ current bi wɔ coil circuit no mu a wɔfrɛ no induced current a ɛkyerɛ sɛ saa nhyehyɛe yi (coil + magnet) yɛ n’ade te sɛ electric generator, electromotive voltage no a ɛda adi sɛ wɔfrɛ no anyinam ahoɔden mfiri a ɛma ahoɔden.
