Are permanent magnets really permanent?

By December 8, 2017Blog

Industrial magnets are incredibly durable and reliable.  In fact, when used correctly and with proper care, they should lose less than 1% of their strength over the course of 100 years!  There are, however, several key factors to prolonging the lifespan of your valuable equipment.

What to avoid to protect your industrial magnet:

Moisture

Liquid permeating the magnet’s housing can cause it to weaken over time.  It’s important to ensure that all seals are water tight, and that no fluid from either the outdoor elements or the manufacturing process can come in direct contact with the magnet itself.

Heat

All magnets, whether ceramic or rare earth, have a temperature maximum that should not be exceeded.  If your product or manufacturing process produces temperatures that are higher than the recommendations for your magnet, you may find the efficacy of your magnetic system will decline more rapidly than expected.

Physical Damage

While magnets are tough, they are subject to damage from mishandling, impact or jarring.  Whether through repairs, processing materials or user error, damage to the internal workings of your magnet may lead to decreased strength and performance over time.

How to care for your industrial magnets

In addition to avoiding heat, water and impact to your magnets, you should also be sure to:

  • Conduct regular inspections of your equipment to make sure that your magnet housing is free of debris
  • Ensure that both self cleaning and manually cleaned magnets are being cleared as they should
  • Check for sharp objects in your conveyor system that could damage the magnet
  • Make sure that bolts are well tightened to prevent instability

Trust your product to the professionals

When it comes to industrial magnets, it’s important to get the advice of an experienced professional to ensure that your design meets your requirements for space, heat allowances and productivity.  A properly designed production line will maximize your square footage while also protecting your magnets from damage and natural elements.
