Self powered pacemaker
By Arihunt Garg & Siyona Malhotra
Electromagnetic induction is the process by which a current can be induced to flow in a wire due to a changing magnetic field.
Thanks to Lenz's law of conservation of energy and Faraday's law of rate of change of magnetic flux through a loop, we know that if we move a Copper wire in a magnetic field, current will be generated.
Keeping the same thing in mind if you move the magnet and the coil is relatively stationery, current will be generated and the bulb will light up
