What Are the Industrial Magnets and Which Industries Are They Applied In?

Industrial magnets are high-impact magnets, and they are the ideal choice for industrial applications for some of their properties. Industries are increasingly using high-impact magnets from physical metal lifting and separation to motor activation and magnetic resonance imaging.

1. Different industrial magnets

Different applications require different types of industrial magnets. Industrial magnets can be divided into two main categories: non-permanent and permanent. Non-permanent magnets are electromagnets that require external current to be magnetized or demagnetized. Permanent magnets include ceramic magnets (it is also known as ferrite magnets), aluminum-nickel-cobalt magnets and rare earth magnets.

Ceramic magnets have lower magnetic force and are more brittle, but they are cost-effectiveness and retain magnetism under corrosion and vibration. Rare earth magnets are less cost-effectiveness to make, but have more power and retain magnetism better than ferrite magnets.

Ammonium magnets are the best and most commonly used magnets in the rare earth industry; Magnets in flake are made of flexible ferrite and plastic composites, they are extruded into sheets and used in the automotive and consumer products industries.

There are many different types of magnetic materials that can be used to make industrial magnets. The most important characteristic that magnet manufacturers consider in their manufacturing process is porosity. And they consider whether it is easy to made. They also consider magnetic retention (or magnetic permanence) under heat, corrosion and vibration. They also take magnetic field strength and the cost into consideration.

2. The application of different types of industrial magnets

The types of permanent magnets are made of different composite materials, which have different properties and applications. For example, ceramic and molybdenum nickel-cobalt magnets are most commonly used for physical lifting and separation. A magnetic tool which performs this job usually consists of multiple magnets in a particular configuration called a magnetic assembly.

The lifting, holding and separating of magnetic components are common in metal fabrication, construction, engineering, automotive, electronics, water treatment, agriculture and other industries. Curved ceramic magnets are commonly used in electric motors, and most stereo speakers use ceramic magnet discs.

Rare earth magnets and magnet assemblies have stronger magnetic fields than ceramic or alnickel-cobalt magnets, and they are used in sensitive electric motors, computer hard drives, television monitors, sensors and medical applications.

Electromagnets are used by the automotive, medical, metal manufacturing, and aerospace industries in solenoid valves, AC and DC motors, biomagnetic separation, beam control, transformers, automotive crushing and so on.
