In the program of high school physics 11th grade, students have learnt the knowledge of paramagnetism, diamagnetism, ferromagnetism and applications of these substances. However, schools are not equipped with laboratory equipment to the teacher using to teach this knowledge. New experiments made so cheaply can provide many of these experiments for high schools. Using lots of experiments in teaching will help students to take part in experimental activities while learning the empirical knowledge of paramagnetism, diamagnetism, ferromagnetism and the applications of these substances.
