Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of auxiliary teaching equipment, in particular to a simulation demonstration device for cutting magnetic induction lines in electromagnetic induction teaching. Background Art
[0002] Magnetic induction to electricity is an important content in electromagnetic induction teaching. When a part of a conductor in a closed circuit moves in a magnetic field to cut the magnetic induction lines, a current is generated in the conductor. This phenomenon of generating current due to the movement of the conductor in the magnetic field is called electromagnetic induction, and the generated current is called induced current.
[0003] However, since the magnetic induction lines are simulated lines and do not actually exist, for the convenience of junior high school students' understanding, the textbook says, "If the magnetic induction lines are imagined as real lines and the conductor is imagined as a knife, it may be more convenient to express." The attached drawings in the textbook can help students understand to a certain extent. However, for a three-dimensional magnet, how exactly does the conductor move to cut the magnetic induction lines? This is still a difficult problem for students to imagine and understand. Teachers also lack corresponding teaching demonstration instruments, and it is very difficult to help students with only language for the situations that need to be imagined.
