Basic Magnetic Field Chamber, 3.625 x 2.3125"

This basic magnetic field chamber contains iron filings sealed inside a transparent cylinder, allowing students to visualize magnetic field lines in three dimensions. A bar magnet up to 0.625 inches in diameter can be inserted into the inner chamber to reveal the surrounding field. A magnet is included. The chamber measures 3.625 inches tall with a 2.3125-inch outside diameter and 0.625-inch inside diameter. The sealed design eliminates loose filings, making it suitable for classroom demonstrations and pass-around hands-on experience in physics classrooms studying magnetism.
