1. What type of envirnoment makes magnets work best?2. What is an electromagnetic field?3. What is a magnetic field?4. What types of magnets are strongest?5. How have magnets changed over the years?
magnet works best in a low temperature envronment free from any magnetic material. an electromagnetic field is one in which the elecric and magnetic components are perpendicular to one another. the modified space around a magnet is called magnetic field. electromagnets are strongest by the years the conventional magnets have been replaced by more powerful electro magnets
cold, magnetism is destroyed at high T it is a field made up of a self sustaining oscillating Electric and magnetic fields (light is one such example) magnetic field is a theoretical construct to explain the force on moving charges in the presence of a magnet. Neodynium (or other such ceramic) OR electromagnet OR superconducting magnet new materials have allowed us to make stronger permanent magnets, superconductors allow strong magnets to be created that do not require continuous power source.
