Hollow Cylinder Magnets – At Low Price | Fullzen

Short Description:

Hollow cylindrical magnets have parallel straight sides and a circular cross-section, and a hollow center section with parallel straight sides.Round cylindrical magnets fit neatly into drilled holes in surfaces such as timber, acrylic or composite materials.Tube magnetic separators are used for separation of ferromagnetic impurities from the material flows flowing in pipes.

We carry a selection of different shapes and sizes and can manufacture magnets to our customers’ specifications.

    hollow cylinder magnets


    How much is a cylinder magnet?

    The cost of a cylinder magnet can vary widely depending on several factors:


    1. Material and Grade
    2. Size and Dimensions
    3. Coating
    4. Quantity
    5. Supplier and Brand
    6. Customization


    Please note that prices can change over time due to factors such as market fluctuations, changes in supply and demand, and advancements in manufacturing processes. To get an accurate and up-to-date price for the specific cylinder magnet you're interested in, I recommend checking with magnet suppliers, manufacturers, or online retailers.

    What is the flux equation for a cylindrical magnet?

    The magnetic flux (

    Φ) through a surface is given by the formula:




    • B is the magnetic field strength (in teslas, T).

    • A is the area of the surface perpendicular to the magnetic field (in square meters, m²).

    • θ is the angle between the magnetic field lines and the normal vector to the surface.

    For a cylindrical magnet, the situation might be a bit more complex because the magnetic field isn't always constant over the entire surface due to variations in the magnetization within the cylinder. In such cases, you would need to consider the integral of the magnetic field over the surface to accurately calculate the magnetic flux.

    If the magnetic field is relatively uniform and aligned with the axis of the cylinder, you might be able to simplify the situation and use the formula mentioned above. However, if you're dealing with a more intricate magnetic field distribution, you might need to work with more advanced concepts, such as integrating the magnetic field vector over the surface.

    Why are silver cylinder magnet stronger?

    Silver is not typically used as a material to make permanent magnets, including cylinder magnets. Permanent magnets, such as neodymium magnets (NdFeB), are usually made from alloys that contain elements like neodymium, iron, and boron. These materials have specific crystalline structures that contribute to their strong magnetic properties.
