Can you do my science project on magnets and temperature?

I'd be happy to provide guidance for your science project on magnets and temperature. You could explore how temperature affects the strength of magnetism in different types of magnets by testing their magnetic properties at various temperatures. This could involve using a magnetometer to measure the strength of the magnetic field at different temperatures, analyzing the data, and drawing conclusions about the relationship between temperature and magnetism.
