The setup demonstrates how a changing magnetic field in one coil generates voltage in another nearby coil, following Faraday’s Law of Induction.\u003cbr\u003e\u003cbr\u003eIt includes essential electronic components such as a 2N2222 NPN transistor, a resistor, a breadboard, copper-wire induction coils, an LED indicator, connecting wires, and a 9V battery. Once assembled, the circuit generates an alternating magnetic field in the primary coil, causing the secondary coil to produce enough induced voltage to illuminate the LED. This provides a clear visual demonstration of mutual induction and transformer-like action. Ideal for STEM education, science fair projects, classroom demonstrations, electronics learning, and physics experiments.","brand":"Project Banao","offers":[{"title":"Default Title","offer_id":41863167803525,"sku":"PB-STEM-MUTUALINDUCTION","price":1999.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0607\/5062\/6949\/files\/Mutual.png?v=1789300393","url":"https:\/\/shop.projectbanao.in\/products\/project-banao-mutual-induction-experiment-kit-with-9v-battery-led-induction-coils-transistor-educational-physics-stem-project-for-students","provider":"Project Banao Store","version":"1.0","type":"link"}
