It is a type of magnetic separator that is installed in a hopper or a pipeline to remove ferrous particles from the material. The hopper magnet is made of high-intensity rare earth magnets that generate a strong magnetic field to attract and hold ferrous particles. The hopper magnet is easy to install and does not require any power source or maintenance.
Magnetic filters are used to separate magnetic particles from liquid or gas streams. They are typically used in industrial processes to remove ferrous particles, such as rust or iron filings, from liquids or gasses. Magnetic filters work by passing the liquid or gas through a magnetic field, which attracts and captures the ferrous particles. The captured particles can then be easily removed from the filter.
A magnetic stick is a magnetic tool used for retrieving small metal objects from hard-to-reach places. It is a handheld tool that has a strong magnet at one end and is often used by mechanics, technicians, and DIY enthusiasts. The magnetic stick is perfect for picking up screws, nails, bolts, and other small metal objects from tight spaces, such as engine bays, machinery, and electronics. The magnetic stick is available in various sizes and strengths, and some models have a telescoping feature for reaching even further.

Magnetic chucks are used in machining applications to hold parts securely in place while they are being machined. Magnetic sweepers are commonly used in manufacturing and construction to collect metal debris from floors and other surfaces.
Magnetic stirrers are commonly used in laboratories to mix liquids. The stirring process is achieved by using a magnetic field to rotate a small magnetic stir bar inside the liquid. Magnetic stirrers are popular because they are low-cost, simple to use, and don’t require direct contact between the stirring device and the liquid, reducing the risk of contamination.
Magnetic particle testing is a non-destructive testing technique used to identify surface and near-surface defects in ferromagnetic materials. It is commonly used in industries like aerospace, automotive, and construction to detect cracks and other defects in metal parts. The process involves applying a magnetic field to the part and introducing magnetic particles that will accumulate at the location of the defect, making it visible.
Magnetic therapy is a medical technique that uses magnetic fields to promote healing and relieve pain. The technique is believed to work by increasing blood flow, improving oxygen supply, and promoting the release of endorphins, the body’s natural painkillers. Magnetic therapy devices are commonly used to treat conditions such as arthritis, back pain, and headaches.
Electromagnets are magnets that are created by passing an electrical current through a coil of wire. They have many applications in various industries. For example, door locks use electromagnets to hold the door closed until an electrical current is passed through the coil to release the lock.

How Magnetic Equipment Works
Magnetic equipment works by creating a magnetic field that attracts or repels ferromagnetic materials. Ferromagnetic materials, such as iron, nickel, and cobalt, are materials that can be magnetized. When a ferromagnetic material is placed in a magnetic field, the magnetic forces cause the material to become magnetized and to be attracted to or repelled by other ferromagnetic materials.
Magnetic equipment uses different methods to create magnetic fields. Some equipment, such as magnetic separators and sweepers, use permanent magnets, which generate a constant magnetic field. Other equipment, such as magnetic lifters and chucks, use electromagnets, which generate a magnetic field when an electrical current is passed through a coil. The strength of the magnetic field can be controlled by adjusting the amount of electrical current flowing through the coil.
In magnetic separators, the magnetic field is used to attract and separate magnetic materials from non-magnetic materials. The materials are passed through the separator on a conveyor belt or in a container, and the magnetic materials are attracted to the magnetic field and are separated from the non-magnetic materials.
Magnetic lifters and chucks work by creating a strong magnetic field that attracts ferromagnetic materials. The equipment is typically made up of a series of electromagnets that are controlled by a central control unit. When an electrical current is passed through the coils, the electromagnets generate a strong magnetic field that attracts the material.
Magnetic sweepers work in a similar way to magnetic lifters, but they are used to collect metal debris from floors and other surfaces. The equipment is typically mounted on a vehicle or a handheld device and is passed over the surface being cleaned. The magnetic field attracts the metal debris, which is then collected and removed.
Magnetic stirrers work by using a magnetic field to rotate a small magnet inside a container. The magnet is typically coated with a material that is not attracted to the magnetic field, allowing it to rotate freely inside the container. A stir bar is placed in the container, and the magnetic field causes the stir bar to rotate and mix the liquid.
Magnetic particle testing equipment works by applying a magnetic field to a metal part and then introducing magnetic particles to the surface. The particles are attracted to areas of the part with defects, making the defects visible and allowing them to be identified and repaired.
Magnetic equipment is an important tool in various industries, from mining and manufacturing to laboratories and non-destructive testing. Magnetic separators, lifters, chucks, sweepers, stirrers, and particle testing equipment all work by using magnetic fields to attract or repel ferromagnetic materials. By understanding how these tools work and their applications, businesses and organizations can make the most of the benefits that magnetic equipment provides.
