In the world of physics, nothing is more fascinating than a conducting loop. Conducting loops can be found in many types of machines, but they are most commonly used to generate electricity from mechanical energy. The first commercial power plant was built on this principle and still operates today! There are two types of magnetic fields that affect conductors: an external field and an induced field. In general, when a conductor moves through an external magnetic field it will induce its own electric current because it has both free electrons and a non-zero resistance. This means that when you use magnetism to create motion with your machine, you simultaneously create electricity! -What is the most common type of machine in which a conducting loop can be found? -Why are they called loops and not coils or circles? -How does an external magnetic field affect conductors, like those in your machine? These effects are also known as electromagnetic induction. -What do you think about when you hear “electromagnetic induction” for the first time? Does it make sense to you now that we have discussed what it means mathematically and practically?” A) What types of machines use a conducting loop to generate electricity from mechanical energy? B) How does this phenomenon work exactly? When a conductor moves through an external magnetic field it induces its own electric current because it
