Lifting magnets have a variety of uses. For example, these magnets can be used to search for metal objects in tanks or places that are difficult for a human being to reach. Lifting magnets can also separate metal particles in oil and water. They can hold wiring and hoses, and these magnets have many applications in industry. A lifting magnet can also be attached to a rod in order to clean a tank. There are two ways that a lifting magnet can be classified. Either a person can measure the magnetic field that the magnet produces or the magnet can be classified by how many pounds the magnet can hold.

One example of a lifting magnet is a junkyard magnet -- a type of temporary magnet otherwise known as an electromagnet. Its magnetic field is approximately one Tesla, which is a strong magnetic field.

A lot of lifting magnets can also be classified according to how many pounds or newtons that the magnet can hold. For example, one websites gave the value 13,340 newtons.
