3D Magnetic Field Lines
★Exhibit Content: Distribution of magnetic field, magnetic field lines ★Interaction: Mechanical interaction ★Operation: 1. Turn the handwheel to rotate the magnet; 2. Observe the changes of the magnetic needles around the magnet. ★Exhibit Description: The exhibit mainly consists of a handwheel, magnet, small magnetic needles, protective cover, etc., demonstrating the distribution of the magnetic field around the magnet and knowledge about magnetic field lines. Visitors turn the handwheel to rotate the large magnet inside the acrylic protective cover. When the magnet rotates, the small iron wires around the magnet move with the magnet, as if they were invisible magnetic field lines. ★Scientific Principle: The magnetic field is a special substance that cannot be seen or touched. A magnetic field exists around a magnet. The magnetic field is a vector field continuously distributed in a certain space. The basic physical quantities describing the magnetic field are magnetic induction intensity and magnetic field lines. Magnetic field lines are defined as lines tangent to the magnetic induction intensity everywhere. The direction of the magnetic induction intensity is the same as the direction of the magnetic field lines, and its magnitude is proportional to the density of the magnetic field lines. The relative density of magnetic field lines indicates the relative strength of magnetism. Under the influence of the strength and direction of the magnetic field, the magnetic needles will produce different distribution curves.
