Description
Technical field
The utility model is related to teaching field, more particularly to a kind of physics education magnetic induction apparatus for demonstrating.
Background technology
Electromagnetic induction, refers to be placed on the conductor in change magnetic flux, can produce electromotive force.Faraday has found to produce in closure
The rate of change of magnetic flux is directly proportional on electromotive force on loop and the curved surface surrounded by any path, it means that when logical
Electric current can flow in any closure conductor when crossing the magnetic flux change for the curved surface that conductor is surrounded.This is applied to itself become on the spot
During change or when conductor is moved inside.Electromagnetic induction is generator, induction motor, transformer and other most of power equipments
Operation basis.
When in use, the motion for cutting magnetic induction line generally requires teacher and holds coil cutting magnetic induction existing device
Line, but typically observed using dial plate, so behind classmate be not readily observed, it has not been convenient to carry out table using whistle
Show the phenomenon of electromagnetic induction, it has not been convenient to allow more classmates to know from experience, reduce efficiency of teaching, magnetic induction line is cut when
Wait, the general scope for being inconvenient to use locating dowel to move coil is adjusted, it has not been convenient to which the size to electric current is adjusted,
Made troubles in teaching process.
