Electric and magnetic fields interact with matter from "summary" of Physics 11 by British Columbia. Schools Department. Curriculum Development Branch
When electric and magnetic fields come into contact with matter, they can interact in various ways. Electric fields are generated by electric charges and exert forces on other charges within the field. When an electric field encounters matter, the charges within the material may rearrange themselves in response to the field. This can cause polarization, where the material becomes electrically polarized with one side having a slight positive charge and the other a slight negative charge. This polarization can then affect the strength and direction of the original electric field. Similarly, magnetic fields interact with matter through the alignment of magnetic dipoles within the material. When a magnetic field is applied to matter, the dipoles may align in the direction of the field, strengthening it, or in the opposite directio...
