BulletPoint1 : [Electric Bell]- Describe the structure and working principle of the demonstration DC bell in physics teaching
BulletPoint2 : [Product Structure]- The electric bell is composed of electromagnet, armature, iron bell, base and other components.
BulletPoint3 : [How To Use]- Use wires to connect the two binding posts to the 4~6V DC power supply, and the power will be turned on, and the bell will sound. During the experiment, if the vibrating shrapnel does not work properly, the distance between the contact screw and the shrapnel can be adjusted so that they can contact and leave normally.
BulletPoint4 : [Notice]- The voltage should not be too high, and the continuous power-on time should not be too long; The contact point of the vibrating shrapnel is in poor contact with the contact screw, and the oxide layer on it can be wiped off with emery cloth.
BulletPoint5 : [Practical Science]- Appropriate physical activities and research are not only fun, but can also enhance students' observation skills, stimulate questions, and connect the content of the book with real life.

Purpose: It is used to describe and demonstrate the structure and working principle of DC bells in middle school physics teaching. It can also be used for air sound transmission experiments with the air extraction device.

Main Specifications
1. The working voltage is DC 3~6V;
2. The electromagnet coil is a DC resistance of 10~20 ohms;
3. When the bell is working, the bell is clear within 15m.
Notice:
1. The voltage should not be too high, and the continuous power-on time should not be too long.
2. The contact point of the vibrating shrapnel is in poor contact with the contact screw, and the oxide layer on it can be wiped off with emery cloth.
3. The electric bell has been debugged and inspected before leaving the factory. Do not disassemble it casually or move the position of the parts.
4. After use, please put it back in the box and place it in a dry place without corrosive gas.
