Industrial Magnets

Definition

Industrial magnets are basically those magnets that are manufactured or engineered for industrial usage. Such magnets are in great demand in today’s market scenario, wherein each type of industrial magnet is used for a different purpose altogether.

Types of Industrial Magnets

Different types of industrial magnets are designed for different purposes. The important ones can be listed as follows:

• ·      Ceramic

• ·      Alnico

• ·      Neodymium

• ·      Samarium cobalt

• ·      Bonded neodymium

These magnets are designed to serve different purposes:

• ·      Individual Magnets

• ·      Bulk Magnet Materials

• ·      Magnetic Assemblies

• ·      Magnetic Sweepers

• ·      Magnetic Lifts

• ·      Magnetic Sheet Handlers

• ·      Magnetic Retrievers

• ·      Permanent Electromagnet Combinations

Characteristics

Industrial magnets posses the following characteristic features:

• ·      Strength

• ·      Brittleness

• ·      Flexibility

• ·      Density

• ·      Tensile strength

Magnet Efficiency

While selecting industrial magnets for different usage purposes, two key aspects should be given due consideration:

• 1.    Magnetic strength

• 2.    Holding force

Magnetic strength or grade refers to the maximum energy product. Holding force refers to the force that the magnet has the capacity to hold under favorable conditions. The holding force of an industrial magnet is highly influenced by the following characteristics:

• ·      Size

• ·      Shape

• ·      Surface Conditions

• ·      Motion

• ·      Vibration

• ·      Friction

• ·      Holding Angles

• ·      Machining Forces

Shapes and Sizes of Industrial Magnets

The shapes and sizes of the industrial magnets can be reflected as follows:

• ·      Button or pot

• ·      Horse shoe or U-shaped

• ·      Magnet blocks or bar flexible strips

• ·      Powder

• ·      Rod

• ·      Rotor or poles

• ·      Sheet or slab

• ·      Round ring or disc

Industrial Magnet Specifications

An industrial magnet mainly embraces the following specifications:

• ·      Length

• ·      Height

• ·      Diameter

• ·      Width

Industrial magnets are basically of three types, viz. non-magnetized industrial magnets, conventional magnetized industrial magnets and multiple magnetized industrial magnets. Once a non-magnetized industrial magnet is assembled within a magnetic circuit, it can be further magnetized. Conventional industrial magnets, on the other hand, have two poles at their either sides and are magnetized through their thickness, length or diameter. Multiple industrial magnets have multiple poles at their either ends.

Industrial Application

Such magnets are well known for its wide range of application for industrial purposes:

• ·      Automotive and electronic sensors

• ·      Computer disc drive

• ·      Electric motors

• ·      In servo motors

• ·      Linear actuators

• ·      Loudspeaker

• ·      Pump couplings

• ·      Rotary motors

• ·      Satellite system

• ·      Sensors
