Physics students will learn how to build a real electric motor that works. It is a hand on experience that guide students step by step in building a paperclip motor. The materials cost about $30, and they are good for 40 students to build their own motors. The best places to buy the wire and the magnets in Ebay, Walmart, and Amazon are indicated with pictures and links. The rest of the material cost practically nothing and are found at home. For the power supply, students can use a D-size battery or the charger of an old cellular phone. How to adapt the cell phone or USB charger is also explained.
The construction of the entire motor takes about 30 minutes. Just follow the pictures and drawings frame by frame, and read the short and clear explanations, and the students will build an excellent motor. The most important part in this learning activity is the making of the coils, and this project explains in detail how exactly the students need to make them in order for the coils to spin smoothly and fast.
This is an excellent activity for physics and physical science students to do in the study of electricity.
