Physics II Quiz Images: Coil of Current-Carrying Wire in a Magnetic Field

Because Canvas is so bad at consistently copying images from one shell to another, here is another set of images used for one of my tests or quizzes.

Version 1:



Version 2:


These depict a coil of wire with N turns which is carrying some current in a uniform magnetic (B) field.

Physics II Quiz Image: Velocity Selector and Charge Spectrometer

Because Canvas has trouble consistently copying images from one shell to another, here is a set of images pertaining to another of my online tests or quizzes:

Version 1:


Version 2:


These both show a velocity selector and a charge/mass spectrometer.

Virtual Lab: Voltmeter from Galvanometer

Since we are on lockdown at Troy University, I have been working on virtual or take-home labs to finish out the semester. I have produced two, which actually allow me to finish the semester. Here is the first of these two:

The basic premise of this lab is simple: I take all of the measurements, but I both overshoot and undershoot. Students must then decide the correct values for these measurements.

Physics II Quiz Images: Velocity Selector(s)

Because Canvas is bad at copying over images from one shell to another, here is yet another set of images which are going to be used for one of my quizzes or tests:

Version 1:


Version 2:


Version 3:


Version 4:


These basically show a velocity selector. There is present a uniform magnetic field in the -z direction, a uniform electric field in the +x direction, and a charged particle moving instantaneously in the +y direction.

Bonus: Here's a few with particle drift.

Version 5:


Version 6:


Lot's of possible questions from these, I think.

Physics II Labs Graph: Inverse Image Distance vs Inverse Object Distance

Because Canvas is so bad at copying images and graphs from one shell to another here is another graph used in one of the quizzes or tests:



This graph is for the image and object distances for a single lens.

Physics II Images: Two Resistors, a Battery, and a Switch

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

Version 1:
Version 2:

Version 3:

All three consist of two resistors in parallel with each other, and a switch which connects or disconnects the second resistor from the circuit.

Physics II Images: 4 Bulbs Connected Together

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

This shows 4 lightbulbs connected to a battery as a circuit diagram. There are other versions of this diagram.

Version 2:
