Subject Area  Electricity & Magnetism 

Level  First Year 
Available Implementation  MATLAB 
Learning Objectives 
Students that complete this exercise will be able to
1. Use computer code to visualize in 3D magnitudes and directions of vector quantities they calculate computationally (Exercises 17)
2. Write the pseudocode for calculating the offaxis electric field due to a charge distribution (Exercise 1).
3. Using the pictures of Efield, develop qualitative reasoning skills, such as using the symmetry of the charge distribution to answer questions (exercise 4)
4. Investigate the effect of a ring consisting of both positive and negative charges, something difficult to do analytically (exercises 57)

Time to Complete  90 min 
These exercises are not tied to a specific programming language. Example implementations are provided under the Code tab, but the Exercises can be implemented in whatever platform you wish to use (e.g., Excel, Python, MATLAB, etc.).
