DEM34 Magnetic Induction of Iron

Objective:

– To show that iron may become a magnet by induction.

Apparatus:

  • Permanent magnet, strong B-field
  • Bar of soft iron
  • Paper clips

DEM34 - Magnetic Induction of Iron

Method:

A bar of soft iron held near a strong permanent magnet becomes a magnet by induction. Paper clips will cling to the ends of the bar as long as the permanent magnet is near enough to magnetize it by induction, but the clips will fall when permanent magnet is removed.
