Description | Students complete the grand challenge of this unit and design an electromagnet to separate steel from aluminum for a recycler. In order to do this, they compare the induced magnetic field of an electric current with the magnetic field of a permanent magnet and then make the former look like the latter. Students complete the grand challenge of this unit and design an electromagnet to separate steel from aluminum for a recycler. In order to do this, they compare the induced magnetic field of an electric current with the magnetic field of a permanent magnet and then make the former look like the latter. They discover that looping the current produces the desired effect and find ways to further strengthen the magnetic field. |
