J6-21: MAGNETIC FIELD IN GAP OF ELECTROMAGNET

j6-21aj6-21bj6-21cj6-21d

Additional Info

  • ID Code: J6-21
  • Purpose: Semi-quantitatively measure the magnetic field in the air gap of a magnet.
  • Description: Using a magnet with a square yoke, separate the top yoke member, creating two gaps in the yoke. Into one gap place a small search coil; into the other place a non-magnetic shim. As the gap length h is increased the field B(gap) decreases:

    B(gap) = mu(0) N i / h, where N is the number of turns and i is the current in the coil.
