Class members use mathematics in order to better understand magnetic forces and their interaction on charged particles. After a demonstration of the interaction between a magnet and an electron beam using a CRT computer monitor, learners tackle example problems relating to magnetic fields and particle motion.

Instructional Ideas

• Divide the class into groups and have them research and present information on the magnetic force on a charged particle, the motion of a charged particle in a magnetic field, and the magnetic force on a current carrying wire

Classroom Considerations

• To demonstrate the deflection of an electron beam, you will need to find an old CRT computer monitor
• The class should be familiar with multiplying with vectors
• The third of a 14-part series

Pros

• The lesson plan includes a set of homework problems and a quiz
• The answer keys show the work needed to arrive at the answer

Cons

• The lesson plan provides lecture information but does not lay out the lecture for the teacher
