Background:
 
What do the students need to know prior to beginning WebQuest? 
  • In a permanent magnet, spinning electrons produce a magnetic field. Likewise, electrons moving through  a wire produce a magnetic field.
  • In an electromagnet,the coil is the source of the magnetic field. An iron is not necessary but is nearly always used

  • because it  intensifies the field. The core is made from material that does not become a permanent magnet.
