Magnetic Field Lines
★Exhibit Content: Magnetic field line distribution, magnetic field characteristics ★Interaction: Mechanical interaction ★Operation: 1. Pick up the bar magnet or round magnet on the table and place it above the magnetic needles; 2. Observe the deflection changes of the small magnetic needles as the magnet moves and rotates. ★Exhibit Description: The exhibit consists of a bar magnet assembly, a round magnet assembly, magnetic needles, a protective plate, a pressure ring, etc. Pick up the bar magnet or round magnet on the table and place it above the magnetic needles. You can see the small magnetic needles deflect along with the magnet. Observe the corresponding changes in the small magnetic needles as the magnet rotates. ★Scientific Principle: Magnetic field lines (magnetic induction lines) are imaginary curves that describe the distribution of a magnetic field. Their density reflects the strength of the magnetic field, and the tangent direction indicates the direction of the magnetic field. A small magnetic needle in a magnetic field experiences magnetic force, and its N pole points in the same direction as the magnetic field at that point. This exhibit visually presents the abstract magnetic field and magnetic field line distribution through the overall deflection of the magnetic needle array, helping to understand the spatial distribution characteristics of the magnetic field.
