New lot of 4 electromagnet electromagnets
For sale here is one lot of four (4) cylindrical electromagnets. Each electromagnet measures 46mm in diameter and 36mm high with two 12mm protruding 4mm x .70 threaded connection terminals. Polymer body encapsulates the laminated steel wound core and includes four steel sleeved 3mm mounting holes in a rectangular configuration on 19mm by 33mm centers. The tripolar ground surface faces are additionally protected by an bonded circumferential steel band 1.75mm thick by 6.5mm deep. The cross-sectional view photo below exhibits the hermetically sealed core windings which are comprised of 132 turns of 24ga solid copper wire having a DC resistance of roughly 1.5 ohms. Zero air gap flat plate loading of one of these electromagnets will generate approximately 14lb of holding force per volt of applied EMF. For example, supplying 6VDC to one of these will exert 84 lb of lifting force. Perfect for student labs or experimentation. Higher duty cycle usage may require a drop resistor.
