Industrial magnets are an important component in the manufacture of several types of technology. They are available in a variety of strengths and sizes, each of which is suited to a different purpose. Understanding the uses of common industrial magnets will help buyers find the right item for their equipment.
Uses for Industrial Magnets
Industrial magnets are an important component in many electronic devices, including computers, mobile phones, and sewing machines. They are also frequently found in cars. Food and drug companies often use magnets to ensure that iron particles are not mixed with consumable products. Strong magnets are integral parts of factory equipment and are often found in conveyor belts.
Understanding Magnetic Strength
The strength of a magnet is commonly measured by its pull force and the strength of the magnetic field. Pull force is defined as the amount of strength it takes to pull a magnet away from a magnetic surface. Magnetic field strength is defined by the size of the magnetic field and how strongly the magnet attracts objects that enter this field.
Electromagnet Industrial Products
Electromagnetic products use electricity to create a strong magnetic pull. Electromagnets only have a magnetic charge when electricity flows through them. The flow of electricity determines the strength of an electromagnet and its voltage. Buyers who need a strong electromagnet should choose one with a high voltage and high number of wire turns.
Permanent Industrial Magnets
Permanent magnets create a persistent magnetic field, which means that, unlike electromagnets, they retain their magnetic properties even in the absence of an inducing current or field. Neodymium magnets are a commonly used type of permanent magnet for industrial environments. They have high concentrations of the element neodymium, which holds a strong magnetic charge. However, pure neodymium tarnishes when it comes into contact with air, so it is commonly mixed with other metals.
Choosing a Neodymium Magnet
Neodymium magnets are available in two main strengths. The weaker rating is N42, which is still strong. It is affordable and a good choice for attracting small metallic objects at close range. The other rating is N52, which is the strongest grade of neodymium magnet available. It is typically more expensive than N42, but has a higher pull force and larger magnetic field.
