Mini Elektromagnet Solenoid

Suction: 350g This kind of small magnet doesn #39;t know how to use it. Its tail is a small piece of strong magnet. When it is not energized, it sucks the iron core, and the strength is not small. When it is energized (red line is connected to the positive pole, blue line is connected to the negative pole), Shielding magnetic, the iron core can move freely, and thus its function is equivalent to a miniature electromagnetic brake: power-on release, power-off brake. (Note: 1. When the red line is connected to the positive pole and the blue line is connected to the negative pole, it is offset by the magnetic. 2. When the blue line is connected to the positive pole and the red line is connected to the negative pole, it is enhanced magnetic. ) We test 3V, the current is 0.17A, but it can #39;t completely offset the magnetic force of strong magnetism. When the current is 4.5V, the current is 0.28A, which can completely offset the magnetic properties of strong magnetism, but it is more prone to heat. Because it is an inventory of goods, the number is not much, we do not have such electromagnetic parameters on hand, please buyers to decide the use of voltage according to their own needs.
