In the past 30 years, the powerful magnets have had tremendous impact on human’s life. Today the magnets are essential components in modern technologies, used in many electric and electronic devices from computers, appliances, to medical equipment. In recent years the emergent applications in renewable energy have come to the landscape, including the large-scale applications in hybrid vehicles, electrical vehicles and wind turbines.
The YouTube videos below show some examples of magnet energy applications, including wind turbines and electric cars. The video on DC motors and generators was made in 1961, and it clearly demonstrates how the magnet energy works for the electric machines; which is also a great teaching material for graduate students.
The PDF file attached below shows a review paper for energy related applications.
