Magnetic Hooks Facilitate Hook for Cruise Home Kitchen Workplace Office and Garage Pack of 15

Product description They are amazingly wonderful for their size and have innumerable uses. It is Ferrite Magnetic hook Grade 5. Data based on scientific measurement Vertical Tension: 22 lbs Horizontal Tension:7 lbs We used A3 high quality steel as the test floor. After many measurements we have obtained scientific and rigorous measurements by pulling the hook at a uniform speed on professional equipment. It is Ferrite Magnetic hook Grade 5. Several Important Factors Affecting the Tensile Force Only when the thickness of the tested steel reaches a certain level the tensile energy can reach the ideal value. Only when the force is perpendicular to the contact surface can the tension reach the maximum. When the force is parallel to the contact surface the pulling force can only reach 1/3 maximum. It can not attract aluminum copper wood plastics and stainless steel. The farther the magnetic hook is from the material the smaller the pull force would be. Therefore the surface paint adsorbed by magnetic hook is also an important factor affecting the pulling force of hooks.
