A new method of showing magnetic field based on ferrofluid
Physics Procedia(2010)
摘要
Based on the visualized magnetic field property of ferrofluid, a new method and a teaching aid of “Three-dimensional Dynamic Ball” is developed to reveal the magnetic field by using self-produced ferrofluid. The ball can show spatial distribution of magnetic field vividly, thus stimulating students’ passion of learning interrelated science and technology knowledge.
