A Basic Guide to Magnetic Strength
If you’re responsible for procuring magnets for your business, you should have a basic understanding of the variables that impact a magnet’s strength. Why? Because strength relates back to safety, reliability, efficiency, and cost-effectiveness. To help you meet your responsibilities and choose the best possible product for your application, we put together this quick and easy guide to magnet strength.
Part One: Gather Information
First, let’s talk about magnetic field and force. The field is a region around the magnet – a moving electric charge – within which the magnetic force acts upon something else. To put it more simply, the magnetic field is the “cause” and the magnetic force is the “effect,” or consequence of the field. Two objects with a charge moving in the same direction exhibit a force of attraction (opposite poles). Objects with a charge moving in opposite directions exhibit a repulsive force (similar poles).
Force and field can both be impacted, which is why you should always begin your product search with a series of questions such as:
- What temperature will the magnet be stored/used at?
- Will it be used in a horizontal or vertical application?
- What shape best suits the application?
- Do you require some type of coating?
- What size magnet do you need?
