About this unit

Magnets are fun and mysterious. But they can do a lot more than just push and pull each other from a distance. In this chapter, we will learn about the intimate relationship between magnets and electric currents. And we will see how we can use this relationship to build amazing things like motors and generators that have become an essential part of our lives today.
