Below are the few questions that must have arosed in your mind at some point while studying physics. These are
- Why does a magnet rotate a current carrying loop placed close to it?
- Why does the secondary winding of a transformer carry a current even when it is not connected to a voltage source?
- How does a bicycle dynamo work?
- How does the Mangla Power House generate electricity?
Let’s perform a simple experiment to investigate some phenomena which can point us towards answers.
