Ferrimagnetism: Ferrimagnetic materials are attracted to magnets and themselves act as permanent magnets. Above the Curie point, ferrimagnetic materials lose their external magnetism. Lodestones (the mineral magnetite, Fe 3O 4) are ferrimagnetic. Powerful magnets which are switchable ON and OFF by simply turning a switch through 90 degrees! This range includes a steel plate lifter, switchable magnetic bases, and magnetic sweepers among others. Ferrofluid is a magnetically responsive liquid that creates the most amazing patterns when placed near a magnet. We have also included some popular magnets here too. Pull force is a reading that relates to the power of a magnet and its ability to move (push or pull) other objects. The pull force of a magnet is determined by the amount of force that would be required to break the magnet free if it was attached to a steel plate. What is Gauss?
High power clamping magnets with removable hooks or eyebolts that are ideal for holding portable lighting, POS signage, and trailing cables among other popular applications. Buschow, K.H.J.

Physical Chemistry Chemical Physics. 11, 4523-4527. doi: 10.1039/B902278C Magnetic metals include some pure metallic elements and their alloys. Here is a list of some of the most magnetic metals:Usually, when people talk about “magnetic metals,” they’re talking about ferromagnetic and ferrimagnetic metals. But, if you include the conditional and weaker types of magnetism, many more metals (and some nonmetals) are magnetic. What Metals Are Magnetic?
Magnets for therapy have been used by thousands of people to provide relief from long term chronic pain caused by a number of persistent ailments. Made from higher grade Neodymium material or in performance increasing assemblies, these magnets have the ULTIMATE magnetic pull force performances. Ferrite does not give the power of Neodymium but it creates deep depths of field and offers outstanding value for money. Popular Magnet Shapes Baird, Christopher S. "Magnetism." AccessScience. Dec. 2019. (Sept. 5, 2022) https://doi.org/10.1036/1097-8542.398800Each and every member of the first4magnets.com team is passionate about magnets. It comes through with every customer we help, every problem we solve and every product we supply. Magnetic behavior depends on conditions. For example, copper metal and salts containing the Cu + ion are diamagnetic, but copper atoms and salt containing copper ions (Cu 2+) are paramagnetic. 304 stainless steel isn’t normally magnetic, but it becomes partially ferromagnetic if it’s bent at room temperature. Are Any Nonmetals Magnetic? Killeya, Matthew. "First Practical Plastic Magnets Created." New Scientist. Aug. 30, 2004.

Everyone at FIRST4MAGNETS ®has a great passion for both magnetics and our customers. We aim to offer the highest quality and customer service available from any UK retailer. How do I choose the right magnet? Clamp the aluminum piece in place using a clamp or vice. This will help keep the aluminum in place while you test the magnet attraction. One practice involves passing a magnet over the cows' food to remove metal objects. Another is to feed magnets to the cows. Long, narrow alnico magnets, known as cow magnets, can attract pieces of metal and help prevent them from injuring the cow's stomach. The perfect range for model makers and model-making applications. You may also want to consider this range for arts and crafts! Phy6.org. "The Great Magnet, the Earth." Nov. 29, 2004. (Sept. 5, 2022) http://www.phy6.org/earthmag/dmglist.htm
Which metals are magnetic?
Pumfrey, Stephen and David Tilley. "William Gilbert: Forgotten Genius." Physics World. Nov. 1, 2003. (Sept. 5, 2022) https://physicsworld.com/a/william-gilbert-forgotten-genius/ Earth's magnetic field, known as the magnetosphere, protects it from the solar wind. According to Wired magazine, some people even implant tiny neodymium magnets in their fingers, allowing them to detect electromagnetic fields. Measure and cut the aluminum pieces to the desired size, using a measuring tape or ruler. If necessary, smooth the surface of the aluminum using sandpaper or a file. A range of stunning notice board magnets, ideal for notice boards, offices or simply super cool for your jazzing up a fridge!
