Hello everyone,
Today I have to connect a solenoid in a machine. It was a 24VDC solenoid. But the problem was the wires have no marking. So I have checked it with a 24V transformer. Regardless of the polarity the solenoid functioned. Which seems confusing for me. Because when we reverse the polarity the magnetic field also reverses, so the plunger must move in the opposite direction.
I have asked my instructor, he told me that, may be this solenoid has bridge rectifier. But I have never seen solenoid with bridge rectifier. I mean normally they consist of just coil. I may be wrong. Has anyone any idea?
Thanks
