Because Canvas is so bad at copying images from one shell to another, here is another set of images used in one of my online tests or quizzes:

Version 1:

Version 2:

Version 3:

Version 4:

Version 5:

Version 6:

Version 7:

All of these show a conductor sliding along a set of rails in an uniform magnetic field.
