Magnetic Fields and Electric Currents, Part 2
Sign in to track this film in your collection or want list.
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.
