Magnetism and electromagnetism:

• What do we call the ends of a magnet?

  Poles
• name the area around a magnet where the magnetic force acts

  magnetic fields
• which end of the magnet do the field lines come out of

  north
• Which end of the magnet do the field lines go into

  South
• what can we use to plot the shape of a magnetic field

  plotting compass
• draw the magnetic field around a bar magnet

  
• compare the magnetic field of the Earth and a bar magnet 


  they are the same
• what shape is the magnetic field around a current-carrying wire

  circular
• is the magnetic force a scalar or vector quantity 


  vector
• what do we call a coil of wire

  solenoid
• what do we call a coil of wire wrapped around an iron core

  electromagnet
• what will increasing the current do to the strength of the magnetic field 


  increase it
• what will increasing the number of turns do to the strength of the magnetic field 


  increase it
