Electromagnetic induction phenomenon demonstration instrument

The invention belongs to the middle school physics teaching apparatus technology field and particularly relates to an electromagnetic induction phenomenon demonstration instrument. The electromagnetic induction phenomenon demonstration instrument comprises a support (1); two coils (2) are suspended on the support (1) side by side; a strip-shaped magnet (3) is arranged between two coils (2); and a closed loop is formed through connection of a lead (4) between the two coils (2). The electromagnetic induction phenomenon demonstration instrument can simultaneously demonstrate phenomenona of generating electricity through magnetism and generating magnetism through electricity and the phenomenon is obvious, direct and interesting. 本发明属于中学物理教学仪器技术领域，特别涉及种电磁感应现象演示仪。该电磁感应现象演示仪包括支架(1)，支架(1)上并排地悬挂有2个线圈(2)，2个线圈(2)的中间位置均设有条状磁铁(3)，2个线圈(2)之间通过导线(4)连通形成闭合环路。本发明能同时演示磁生电和电生磁现象，而且现象明显、直观性好、趣味性强。
