The cast Alnico 5 U-shaped magnet with red coating offers high heat resistance and medium magnetic pull, and comes with a keeper to retain magnetic strength. The magnet provides a maximum of 3 lb. of pull strength to a perpendicular surface (pounds of pull strength does not apply to shear force). The magnet can withstand temperatures up to 975 degree F. Resistance to demagnetizing is low and resistance to corrosion is high.
Alnico magnets are made by casting or sintering aluminum, nickel, and cobalt with iron and small amounts of other metals to enhance the magnet grade’s specific properties. Magnetism is very stable in Alnico magnets, even in high-temperature technical applications. They can be formed in fairly complex shapes and produce highly magnetic fields in certain configurations. Alnico magnets are easily de-magnetized and re-magnetized. Alnico magnets can be plated with a variety of metals or given a coating that is usually red. They do not corrode.

I needed this for a science project. It's small and can fit in a pocket, however, does not have that strong of a pull. It was ok for me.

We used this magnet for a school project. It worked great! It picked up every object we needed it to. It was smaller than I expected but true to the stated size. The kids liked the horseshoe shape.

This is a small horse shoe magnet which was reasonable in price. It has a strong magnetic field. It is very useful for picking small nails and pins from the floor. If you spill a box of wire brads, they are very to pick up with your fingers. Well, this magnet makes that chore easy. I work with stones, which I polish. Many times, stick pins which I use to display polished rocks which I put in small plastic bags, will spill onto the floor or into a pile of unsorted stones. The magnet pulls all of the pins right out of the pile, leaving the stones behind. And I don't get any pins in my fingers. Over all, this an item which should be found in workshops and craft workrooms. The magnetic pull is very strong. For a small magnet, it is a good buy

It's a strong magnet for it's size, But I was thinking it would be bigger & stronger. I lost it after about 3 weeks because I drink too much liquor & the magnet is quite small, If it were a few bucks cheeper- I would give it a higher rating. 3 stars, on the real.

My child accidentally dropped the packet on the floor and when we opened it up, the magnet was broken in two. It was less than a two foot drop. Disappointed.

I was looking for a basic U-shaped magnet that I could use to teach my 5 year old. It has a strong magnet force and it a great size. We had a great time learning with it!

I wasn't expecting much for my money on this but it served its purpose in my Grinch Escape Rooms when it was tied to a ribbon to remove a small key from a cup in order to gain access to a hidden object. A little tape worked well to finish the game.
