Material	Plastic & mental

Experimental operation
1. The relationship between the magnetic force of the electromagnet and the number of turns of the coil.
Experimental equipment: 1 piece of shoe-shaped iron core, 2 pieces of wire wraps, 1 piece of No. 1 battery and box, 1 piece of single-pole switch, several wires, several pins.
A simple circuit is formed, and the middle tap of the wire package is used to connect the circuit twice to conduct experiments, so as to absorb the pins (one after another), and the relationship can be judged through experiments.
2. The relationship between the magnetic polarity of the electromagnet and the direction of the current.
Experimental equipment: 1 cylindrical iron core, 1 wire package, 1 No. 1 battery and 1 box, 1 single-pole switch, several wires, and 2 small magnetic needles.
The equipment is combined into a circuit, and the small magnetic needles are placed outside the two ends of the iron core. After power-on, it can be seen that the magnetic needles are deflected and then stagnant in orientation. In this way, the magnetic pole direction of the iron core can be judged, the circuit can be readjusted, and the positive and negative phases of the battery wiring can be adjusted. , and then determine the orientation of the small magnetic needle at this time after power-on, so as to obtain the experimental results.
3. The relationship between magnetic strength and current
Experimental equipment: 1 student power supply, 1 DC ammeter, 1 sliding rheostat, 1 cylindrical iron, 1 set of wire wraps, some wiring, and some pins.
Combine the circuit according to the wiring requirements, take the DC 6V voltage, slide the varistor to the minimum resistance position, after power-on, suck the pins (one after another), and then slowly slide the varistor saddle to continuously reduce the current until there is no current. Through the circuit, it can be seen that in the above process, the pins have been sucked in a long string, and then dropped one by one until there is no magnetic force, so as to achieve the purpose of the experiment.

Product feature and application
This instrument is a matching equipment according to the experimental content of the new syllabus, and is used for students' experiments in electromagnetics teaching in middle schools.

Maintenance and precautions
1. When using dry batteries for experiments, do not power on for too long to prevent the battery from drying out.
2. After the experiment, place the supporting device in the specified position to avoid damage to the device.
