Product Pictures
This product is designed according to the new standard of the State Education Commission, has the characteristics of reasonable structure, excellent performance and easy to use, especially the remarkable performance of small residual magnetic force, and the use of a single group can do bar magnet experiment, so that students can intuitively understand the characteristics of electromagnets.
The experimental apparatus can explain the basic structure and principle of the shoe electromagnet and the bar electromagnet.
During the maintenance test, the continuous working time should not be too long, so as not to destroy the coil. After use, the end face of the iron core should be coated with anti-rust oil, so as not to affect the use effect.

1. Suction test:
(1) Operating conditions: the working voltage DC is not greater than 3v, the working current is not greater than 650mA(2) The DC power supply is connected to the two terminals of the electromagnet in series or parallel, the line is energized a little first, and the armature is absorbed, so that the armature hook is located in the middle of the two magnetic poles in both directions.
And hook the weight of 250g or less, adjust the voltage at both ends of the coil to gradually increase the current to 650mA, lifting the weight of the voltage value is not more than 3v.
2, core residual magnetic test: after the suction test, do not cut off the power, replace the weight, weight and armature total weight 270g, and then cut off the power, replace the weight, weight and armature total weight 270g, and then cut off the power, the armature should automatically leave the core.
