This statement is true for any lifting magnets because they all operate on the same fundamental laws of Physics. Magnetic power is pictured as lines of force flowing from North to the South Pole. Anything that limits the flow of these magnetic lines of force obviously reduces the magnet’s lifting ability. There are four important factors that limit the flow of these lines of force.\u003c\/p\u003e\n\u003ch4\u003eLoad Surface Conditions\u003c\/h4\u003e\n\u003cp\u003eMagnetic lines of force do not flow easily through the air, they need iron in order to flow freely. Therefore, anything that creates an air gap between a magnet and the load, limits the flow of magnetic force and thus reduces the lifting capacity of a magnet. Paper, dirt, rust, paint and scale act in the same way as air, so also a rough surface finish between the magnet and the load.\u003c\/p\u003e\n\u003ch4\u003eLoad Length and Width\u003c\/h4\u003e\n\u003cp\u003eWhen the length or width of a load increases, it ceases to lie flat and the load begins to drop at the edges. The drooping\/sagging of the load can create an air gap between the load and the magnet. If this occurs then the lifting capacity of the magnet is reduced.\u003c\/p\u003e\n\u003ch4\u003eLoad Thickness\u003c\/h4\u003e\n\u003cp\u003eMagnetic lines of force are more effective when they flow through iron instead of air. The thicker the load, the more the lines of magnetic force. After a certain thickness of load, no more lines of force will flow because the magnet has reached its full capacity. Thin material (load) means less iron available and thus fewer lines of magnetic force flow from the magnet into the load. Therefore, the lifting ability of the magnet is reduced. Every magnet is rated for minimum thickness of load to reach full lifting capacity. Below such thickness of load will berate the lifting capacity of the magnet. In general, it can be said the load must be thicker than the width of one of the magnet poles.\u003c\/p\u003e\n\u003ch4\u003eLoad Alloy\u003c\/h4\u003e\n\u003cp\u003eLow carbon steels, such as soft Iron or Mild Steel are nearly as good conductors of magnetic lines of force as pure iron. However, if the alloys contain nonmagnetic materials, they decrease the ability of magnetic lines of force to flow into the load. An alloy such as ANSI \u003cspan data-mce-fragment=\"1\"\u003e1020 \u003c\/span\u003eof Stainless steel is an almost as poor conductor of magnetic force as air.\u003c\/p\u003e\n\u003ctable class=\"tg\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd colspan=\"2\" style=\"text-align: center;\"\u003eThis table provides reduction factors for material other than AISI 1020 Steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd colspan=\"2\" style=\"text-align: center;\"\u003eReduction factors for materials other than AISI 1020 steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: center;\"\u003eMaterials\u003c\/td\u003e\n\u003ctd style=\"text-align: center;\"\u003eReduction Factors\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: center;\"\u003eCast Steel\u003c\/td\u003e\n\u003ctd style=\"text-align: center;\"\u003e0.90\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: center;\"\u003e3% Silicon Steel\u003c\/td\u003e\n\u003ctd style=\"text-align: center;\"\u003e0.80\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: center;\"\u003eAISI 1995 Steel\u003c\/td\u003e\n\u003ctd style=\"text-align: center;\"\u003e0.70\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: center;\"\u003e416 Stainless Steel\u003c\/td\u003e\n\u003ctd style=\"text-align: center;\"\u003e0.50\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: center;\"\u003eCast Iron (Non-chilled)\u003c\/td\u003e\n\u003ctd style=\"text-align: center;\"\u003e0.45\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: center;\"\u003ePure Nickel\u003c\/td\u003e\n\u003ctd style=\"text-align: center;\"\u003e0.10\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch4\u003eWhy PML’s Permanent Magnetic Lifters?\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eThese magnetic Lifters are ruggedly built\u003c\/li\u003e\n\u003cli\u003eHigh Lifting Capacity with respect to size \u0026amp; weight\u003c\/li\u003e\n\u003cli\u003eWorks without Electrical Power\u003c\/li\u003e\n\u003cli\u003eNo maintenance and operational costs\u003c\/li\u003e\n\u003cli\u003eVery easy to use - Save time \u0026amp; energy\u003c\/li\u003e\n\u003cli\u003eMade with high energy rare earth magnets (NdFeB)\u003c\/li\u003e\n\u003cli\u003eMechanical Switching by turning a lever with a lock\u003c\/li\u003e\n\u003cli\u003eThe system against switching off accidentally\u003c\/li\u003e\n\u003cli\u003eNo damage to the work piece being lifted\u003c\/li\u003e\n\u003cli\u003eEasily transportable\u003c\/li\u003e\n\u003cli\u003eReliable\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PML","offers":[{"title":"812-2 (300kgs)","offer_id":32872165212238,"sku":"","price":21800.0,"currency_code":"INR","in_stock":true},{"title":"813-3 (600kgs)","offer_id":32872165245006,"sku":"","price":35650.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0309\/7625\/products\/300kg-doublecircuitlifter.png?v=1612778081","url":"https:\/\/shop.pmlindia.com\/products\/double-circuit-magnetic-lifter","provider":"Permanent Magnets Ltd","version":"1.0","type":"link"}
