Instructions
This experimental apparatus is equipped with a 9V DC power supply, and can also be used with other supporting controlled instruments (such as indicator lights, demonstration motors, etc.) to carry out diversified electromagnetic control demonstration experiments.
Close the switch K4, the current passes through the electromagnet M to generate magnetism, and the armature P is attracted downward, so that the normally open controlled circuit is connected.
Disconnect K4, the current disappears, the electromagnet M loses magnetism, the spring B pulls the armature P upward, the normally open circuit is disconnected, and the K2 contact is connected to the normally closed circuit.
Adjust the spring screw on the iron core to control the expansion and contraction of the spring, so as to ensure good contact state of the normally open and normally closed contacts and maintain stable experimental performance.
