Question

2. The picture to the right shows a Forever Flashlight which is "charged" by shaking the flashlight. Inside the flashlight there is a magnet that moves through a coil. There is also a capacitor and an LED for the light source. Please use words and the appropriate equations to describe how the flashlight works (the charging system) Note you will have to use at least one of Maxwell's equations in differential form and will need at least one of the anc illary equations as well Where does the electricity" cone from? How is the current related to the motion? [20]

Answer 1

The given picture to shows of Forever Flash light with transparent barrels The moving magnetic field line (flux pattern) cuts through the wires. causing electro induction, when you shake the flashlight, actually you will realize. That magnet passes or doing & for the motion through a loop wire The permanent magnet is inside a platonic traces which allows it. The light slide up and down. when you shake the flashlight, the magnet passes through a capper wire repeatedly The electrical energy produced is stored in a capacitor That can be charged of times \r\n Average 30 sec of shaking provides a full charge and produce a beam of light for several hours/minutes Principle: Michael faraday disconnected that by passing a magnet through a coil of wire, A small current is created the same thing happen when person shakes a flashlight Basic components that you needed for shaking flashlight are 1. Magnet. 2. coil - copper 3. Capacitor 4. Switch &
