Magnets For Crafts

Craft Magnets & Flexible Magnets

Traditionally, craft magnets were made of Flexible or Ceramic magnetic materials. But with the dramatic decreases in the price of Neodymium, these powerful magnets are now a part of the crafter's tool-kit. Neodymium magnets are by far the strongest, followed by Ceramic, and then by Flexible or rubberized magnets. Flexible magnets are more convenient to use - being easy to cut and adhere - and the most economical.

If your project is intended to hold several sheets of paper to a refrigerator door, we recommend using Ceramic or Neo magnets, since these will function much better through several sheets of paper.


Holding Force Tips

The Flexible magnetic strip magnets have a holding force of about 12 ounces per square inch of material when in direct contact with an unpainted, flat mild-steel plate. When in contact with a steel plate that is painted with a normal thickness of paint, this reduces to about 8 ounces per square inch.

Thus, if using a strip that is 1/2" wide, you can figure on getting about 4 ounces of pull from a 1" long strip. To get more, simply use more!

Here is a calculator you can use to calculate how much material you will need to purchase based on how much pull you need, how wide you want the magnet to be, and how many pieces you need to make. (Note: you should always check the actual pull on the type of surface you want to attach to before starting production - the pull can vary a great deal depending on the surface condition!)

For Flexible Magnetic Strip that is 1/16" (0.06") thick
I need ounces of pull
I want to use material that is inches wide
I need to make pieces
You need to use at least inches of material per piece
You need feet of material altogether
You need to purchase 100-foot rolls of material

Easy to Cut, Available with Adhesive Backing

Flexible strip magnets are easy to cut to length with a knife or scissors. You can also purchase this material with a high-tack adhesive backing that makes it very easy and convenient to adhere to your product. No messing with glue sticks or other adhesives! And we can cut (or score) the material for you to your specified length.


Holding Force Tips

Approximate holding forces for each of the ceramic magnets listed in the Products sections are shown for each part number. Here is a summary:

Disc Shaped Magnets
Part Number Material Diameter
12-F Flexible 0.50 0.25 3
F-5010 Ceramic 0.50 0.19 9
35DNE0606-NI Neodymium 0.10 0.10 12
F-7506 Ceramic 0.71 0.20 13
F-10015 Ceramic 1.00 0.16 14
35DNE1606-NI Neodymium 0.25 0.10 31
35DNE3208-NI Neodymium 0.50 0.13 78

Remember that these are guides only and actual holding forces will vary depending on the thickness of the metal you are attaching the magnet to, any paint on the metal surface, and other factors. For safety, always go to the high side by selecting a magnet with the maximum holding force given the weight of the product that will be attached to it. And always test the magnets on your actual product and application since there are many variables that could change the pull force!

For especially large and heavy items, you can use two magnets, placed so that they attract each other when side by side. This way you can get more than twice the holding force!

Adhering Ceramic Magnets to Your Product

Hot glues work well with most surfaces and Neo and Ceramic magnets. "Super Glues" (such as Loctite) also work well with these magnets and non-porous surfaces such as metal. Always test the glue and magnet before making a final selection and make sure that all surfaces are clean so that you get a good bond.


Use more magnet - larger pieces of rubber strip or several Neodymium or Ceramic magnets on your product. Or send us your inquiry and we may be able to make cost effective suggestions for you. We stock a very large variety of magnets in various sizes and materials - we have something that will work for just about any project!
