Description: Shows how magnetic fields interact in both permanent magnets and electro-magnets and describes how the interference of opposing fields is used to operate an electric motor. Includes examples using iron filings and glass plates to show the presence of magnetic fields in a variety of situations, from a permanent magnet to coils of wire., This film investigates what happens when magnetic fields interact. The effect is studied by observing the magnetic fields of permanent magnets which are attracting and repelling other magnets.

Complete Record: Shows how magnetic fields interact in both permanent magnets and electro-magnets and describes how the interference of opposing fields is used to operate an electric motor. Includes examples using iron filings and glass plates to show the presence of magnetic fields in a variety of situations, from a permanent magnet to coils of wire., Investigates what happens when magnetic fields interact. The effect is studied by observing the magnetic fields of permanent magnets which are attracting and repelling other magnets. The principles demonstrated are used to explain the operation of a simple electric motor., This film investigates what happens when magnetic fields interact. The effect is studied by observing the magnetic fields of permanent magnets which are attracting and repelling other magnets.NOTE: Two (or more) records have been merged together to create this data.
