The phenomena, concepts and principles of electricity and magnetism are reviewed, illustrating some of their applications -some of them related to living systems- along the way Following the historical order, forces and energies associated with electric charges at rest, with electric charges moving inside conductors, with permanent magnets and
However, research to improve students’ understanding of electricity and magnetism is limited compared to introductory mechanics This thesis explores issues related to students’ common difficulties in learning some topics in electricity and magnetism and how these difficulties can be reduced by research-based learning tutorials

Some key facts and conclusions about electric and magnetic fields from power lines: ○ EMF levels decrease rapidly the further you are from the source
A circuit that has only one path that electricity can follow If one burned out bulb causes all of the lights to fail in a circuit, what might you conclude?
Each light switch in the classroom allows you to turn on one row of lights What conclusion can you make about how the rows of lights are connected?
Magnetism and electricity can produce energy of motion Electromagnet: a What can you conclude about the electric charges on the balloon and on the wall ?
