Magnetic and Non-Magnetic Materials

This video tutorial, presented by Pak Harga, covers the topic of magnetic and non-magnetic materials. It begins with an introduction to the learning objectives, which aim to help students identify magnetic and non-magnetic objects. The video explains that magnetic materials can be classified into ferromagnetic, paramagnetic, and diamagnetic categories, with examples provided for each. Non-magnetic materials, such as wood, plastic, and rubber, are also discussed. The tutorial concludes with an interactive exercise encouraging students to classify objects as magnetic or non-magnetic, followed by a summary and closing remarks.
