Brief description
Fig. 1 is circuit theory diagrams of the present utility model.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings and by specific embodiment.
A kind of electromagnetic energy conversion device, as shown in figure 1, including inductance coil L1, the two ends of this inductance coil in parallel by
Resistance R1, the series circuit of light emitting diode D1, the two ends of this inductance coil are also in parallel to be connected by resistance R2, light emitting diode D2
Circuit, the opposite polarity of described light emitting diode D1, D2；The two ends of this inductance coil be also connected with by diode T1, T2, T3,
The full bridge rectifier that T4 is constituted；The two ends of this full bridge rectifier also shunt capacitance C1；The two ends of this full bridge rectifier are also
Parallel connection is by the series circuit switching K1, light emitting diode D3, resistance R3.
In the present embodiment, for the ease of student viewing test effect, described D1 is red light emitting diodes, and D2 sends out for yellow
Optical diode, D3 are white light-emitting diode.
Described C1 is a large value capacitor, can be the super capacitor of 2000F, have energy storage function.
Using method of the present utility model is：
1st, by when in one piece of permanent-magnet block A speed insertion inductance coil, inductance coil produces the electric current of a direction, and point
Bright light emitting diode D1 (or light emitting diode D2)；
2nd, when extracting permanent-magnet block, inductance coil produce rightabout electric current, and light light emitting diode D2 (or
Light emitting diode D1)；
Student can be helped intuitively to learn Lenz's law with the direction of verificating current by the plug of permanent-magnet block；
When repetitious plug permanent-magnet block, inductance coil alternately produces the electric current of positive and negative direction, now electricity
Flow through the full bridge rectifier of T1 to T4 composition, and charge to C1, because condenser capacity can maintain greatly the electricity of a period of time
Amount, can light light emitting diode D3 when K1 closes.
This experimental provision verificating current direction, the thermal energy storage process of checking electric capacity, multiple plug permanent-magnet block can generate electricity.
This utility model design science rationally, be skillfully constructed, clear and intuitive, be easy to make, make student clearly can watch test effect,
It is easy to student and understands and masters main points, effectively motivate students' interest in learning.
It is emphasized that embodiment described in the utility model is illustrative rather than determinate, therefore this reality
It is not limited to the embodiment described in specific embodiment with new inclusion, every new according to this practicality by those skilled in the art
The other embodiment that the technical scheme of type draws, also belongs to the scope of this utility model protection.
