  • The magnetic field is a region where other magnets or magnetic materials experience a non-contact force
  • The force between two, unlike poles, is attractive
  • When a compass is far away from a magnet, it points north
  • The force between a magnet and a magnetic material is always attractive

Basic Electromagnetism

  • The magnetic field goes around a current, carrying wire in circles
  • Adding more turns to a solenoid increases the strength of its magnetic field because of the field lines around each loop of wire line…
