Magnetic Field
Students explore how compass and Gauss meter detect a magnetic field. In this physics lesson, students build their own Gauss meter and sensor based on given procedure. They cite real world applications of magnetism.
Curated OER
Magnetic Fields and Bermuda Triangles
Students map magnetic fields of a magnet using a compass and predict where fields cancel each other to create 'Bermuda Triangles'. In this magnetism lesson, students use a compass to map the magnetic field of a magnet. They explain how...
