Abstract
The utility model discloses a device of demonstration electromagnetic induction principle, the device include base, handle, electromagnetic induction device, voltmeter, touch piece, coil, wire, electromagnetic induction device, voltmeter, touch piece are located the base, and the handle links to each other with electromagnetic induction device, and the coil is located electromagnetic induction device, and the coil passes through to form closed -loop with voltmeter, touch piece after the wire links to each other respectively. Because the structure is used, the utility model discloses demonstrate vividly directly perceivedly, the student is convenient for master the knowwhy, simple structure moreover, convenient operation.
Description
Technical field
The utility model relates to a kind of teaching demonstration device, particularly relates to a kind of device of demonstrating electromagnetic induction principle.
Background technology
In current teaching, due to electromagnetism be cannot see touch less than thing, be a teacher when explaining electromagnetic induction principle, for the student just touching this respect knowledge, indigestion, teacher is also difficult to image, lively explanation, this brings certain difficulty to teaching, in order to student can be allowed to carry out theories of learning knowledge by macroscopic appearance, we have devised a kind of device of demonstrating electromagnetic induction principle in teaching for many years.
Summary of the invention
The purpose of this utility model is to provide the device of directly perceived, the lively demonstrating electromagnetic induction principle of a kind of energy.
The purpose of this utility model is achieved through the following technical solutions, the device of this demonstrating electromagnetic induction principle comprises base, handle, electromagnetic induction device, voltage table, touch block, coil, wire, described electromagnetic induction device, voltage table, touch block are positioned on base, handle is connected with electromagnetic induction device, coil is positioned at electromagnetic induction device, coil by wire respectively with voltage table, touch after block is connected and form closed-loop path.
When turning handle, cutting magnetic line movement made by coil, produces induction current in coil, and induction current forms closed-loop path after voltage table, touch block, when people catches tactile touch block, just has numb sensation.
The beneficial effects of the utility model: owing to adopting said structure, the utility model demonstration is lively directly perceived, and student is convenient to grasp knowwhy, and structure is simple, easy to operate.
