The Amoeba Sisters strive to facilitate curiosity and engagement by making biology both humorous and meaningful. The videos use real world examples and silly cartoons to demystify difficult biology concepts, such as cell anatomy, homeostasis, enzymes, and biomolecules. A new video is released weekly. The creators are sisters who both work in education. One is a high school biology teacher who found these videos made biology more approachable and easier to comprehend.

The lesson begins with a demonstration introducing students to the force between two current carrying loops, comparing the attraction and repulsion between the loops to that between two magnets. After formal lecture on Ampere's law, students begin to use the concepts to calculate the magnetic field around a loop. This is applied to determine the magnetic field of a toroid, imagining a toroid as a looped solenoid.
