Learn the fundamentals of energy in an inductor and magnetic field density in this beginner-friendly physics tutorial! In this video, we break down key concepts, formulas, and examples to help you ...

How can you produce a magnet with exactly the right magnetic field? A research team now has a solution: for the first time, they have created magnets with a 3D printer. Today, manufacturing strong ...

This means that their magnetism is there all the time and cannot be turned on or off as it can with an electromagnet. Converting a magnet to a non-magnet is called demagnetisation. Magnets are made ...
