Magnetic Effects

Students will learn about ferromagnetism by experimenting with the forces exerted by magnets on each other and by magnets on iron objects. They will also investigate how and why magnetic compasses work. They will see how magnetic forces get weaker with distance and how they can be exerted through non-magnetic substances. Finally, they will build a simple electromagnet to see how electricity can be used to make a magnet. Some applications of electromagnetism in their everyday lives will be discussed.
