Week 3 - Overview and Research


                 
            This pas week we searched for magnets. We were thinking of using Neodymium magnet that is 1.25 T, which is considered to be a very strong magnet. However, we are considering other options too. Furthermore, we bought shake flashlight from amazon to get an idea of what our charger should be like. In addition, we have a Creo sketch of our charger that can be seen in figure 1. We found much useful information for our project for example: 1.1 Amps charge the phone 1% per minute. In addition, we decided to take off the capacitor from the shake flashlight we bought and use it for our project because it is a perfect match (1F and can store up to 5.5V). After doing some tests we will decide whether to have a switch or whatever charge is on the capacitor goes straight to the phone. In addition, if we are going to use a battery we might not need a capacitor. Finally, we divided tasks and discussed the scientific aspects of our project when we met outside the lab. Along with our side work, we also researched faraday's law.
