A homopolar motor is built with a battery, a magnet and some conductive wire. The magnet provides a magnetic field that will interact with the magnetic field induced by the current in the wire.
A homopolar motor is a type of electric motor that uses a magnetic field to create motion. It is also known as a disc motor, a Faraday disk, or a disc dynamo.
The homopolar motor is made up of three main parts:
A battery: This provides the electrical current that flows through the wire.
A magnet: This creates the magnetic field that interacts with the current in the wire.
A conductive wire: This is the wire that carries the electrical current and interacts with the magnetic field.
The wire is typically shaped into a disc, and it is placed between the poles of the magnet. When the battery is connected to the wire, a current flows through the wire. This creates a magnetic field around the wire. The magnetic field of the wire interacts with the magnetic field of the magnet, and this causes the wire to rotate.
The speed of the homopolar motor depends on the strength of the magnetic field, the amount of current flowing through the wire, and the size and shape of the wire.
Homopolar motors are simple to construct and can be used to generate small amounts of electricity. They are often used in educational demonstrations and experiments.
Here is a diagram of a homopolar motor:

3 Main Ideas from "Decolonising Science Communication in the Caribbean: Challenges and Transformations in Community-Based Engagement with Research on the ABCSSS Islands"
Decolonizing science communication in the Caribbean
Science communication often excludes local contexts and voices. Researchers fly in, collect data, and leave without meaningful engagement. This "helicopter science" echoes colonial practices.
Decolonizing science communication means centering local knowledge, needs and perspectives.
Challenges in nature conservation communication
Nature conservation relied on "fortress conservation" to create parks without local input. This leads to conflict and lack of public engagement.
Research agendas are often dictated by foreign interests and lack local impact.
Transforming mental health care communication
Mental health care communication often excludes local cultural beliefs. Historical mistrust of healthcare systems deters access.
New efforts like translating materials into local languages can help make communication more inclusive.
Advocate for science communication that engages local populations as equal partners.
Please let me know in the comments which article I should tackle next!
