Magnetism Basics

Cards (9)

  • What 3 metals are magnetic?
    Iron, Nickel, Cobalt (induced magnets)
  • Why is Steel magnetic?
    steel is an alloy of iron
  • What piece of equipment could we use to find the direction of a magnetic field
    a compass
  • What is a Permanent Magnet?
    This is a magnet that always creates a magnetic field
  • What is an Induced Magnet?
    When a magnetic material is in a magnetic field, it becomes a magnet itself. It stops becoming a magnet when it is out of the magnetic field
  • What is a Temporary Magnet?
    This is the name of any magnet that can stop being magnetic. It could either be an induced magnet or an electromagnet
  • Experiment- When you hold up a permanent magnet and attach paperclips (magnetic material)to it, the paperclips become induced magnets so they are able to attract each other but the further away the paperclips get from the permanent magnet, the attractions between the paperclip weakens.
  • When drawing field lines, when the lines are closer together(more concentrated), the field is stronger
  • Field lines always go from positive to negative
