A magnet and a magnetic handle are related but differ in their construction and application. A magnet is an element made of a magnetic material that possesses magnetic properties, such as attracting ferromagnetic metals like steel, iron, cobalt, and nickel. Magnets are used in various fields, including electronics, medicine, the automotive industry, and many others.
A magnetic handle is a magnet or a set of magnets with a housing attached to it, providing safety during use. The housing protects the magnet from damage and cracking, which is particularly important for brittle magnets. A magnetic handle may also have additional features such as threads, handles, or ears that facilitate its installation and use.
The biggest advantage of magnetic handles compared to magnets alone is their higher lifting capacity. Magnetic handles have a construction with a magnetic circuit made of a magnetically hard material, such as a magnet, and a magnetically soft material, such as low-carbon steel containing a significant amount of iron. The magnetic circuit increases the magnet's attractive force, enabling magnetic handles to hold heavier objects.
However, magnetic handles also have disadvantages compared to magnets alone. They have a shorter range of action because the lines of magnetic force close very flatly, resulting in much weaker magnetic induction at greater distances from the magnetic handle's surface.
In summary, a magnet and a magnetic handle differ in their construction and application. Magnets are used in various fields where magnetic properties are required, while magnetic handles are used for holding heavier objects due to increased magnet's attractive force but have a smaller range of action.
