CHAMPAIGN, Ill. (WCIA) - Why's Guy Paul Kwiat came on the morning show to show us how batteries how batteries affect magnets. Traditional magnets used in DC motors will lose their magnetism eventually. They can be re-magnetised, and sometimes you can get modern ... Old-style "permanent" magnets slowly weaken over time. If they are handled roughly they will lose magnetism much more quickly. Vibration, heat ... Ionizing radiation can damage the body's DNA and cells, which may contribute ... But the electric and magnetic fields in ELF radiation can act independently. In this experiment, you will make an electromagnet. Then you will test how changing two variables can affect its strength. Safety: Electromagnets can get hot ...
