What are the uses of magnets in industry? What are the shapes of magnets?

Magnets are a kind of magnet that can attract metals. They are mainly used in speakers, compasses, magnetic needles, magnetic toys, motors, leather bags, electric bells, door stops, induction cookers, generators, etc. And they come in a variety of shapes. Let's take a closer look at what shapes they have.

Uses of magnets in industry

Magnets and magnetic technology are widely used in the mining industry, and powerful magnetic separators are often used in many coal mines, especially coal mines. Magnets are also used to manufacture various industrial products, such as electric motors, electric guitars, pickups, sensors, speakers, automotive and electronic sensors, Hall effect sensors, magnetrons, etc.

Magnets can separate magnetic materials from non-magnetic materials by their own properties. Magnets are used in the mining industry to separate metals and ores.

Food manufacturers use magnets to prevent small iron particles from mixing with food. Suppliers use magnets to separate coins from other trash.

Magnetic technology is also widely used by the food production and pharmaceutical industries to remove excess iron that would otherwise contaminate their products.

There are several shapes of magnets

There are six common types: ring magnets, button magnets, horseshoe magnets, bar magnets, square magnets and round magnets. In addition, magnets are divided into permanent magnets and non-permanent magnets. Permanent magnets, also known as natural ores, can also be artificially made. Non-permanent magnets only have magnetism under certain circumstances.

Magnets were not invented by humans, but are natural magnetite. The ancient Greeks and Chinese discovered that there is a kind of naturally magnetized stone in nature, which they called "magnets". When they were randomly moved, they always pointed in the same direction.

Early sailors used this magnet as the earliest compass to identify directions at sea. The first people to discover and use magnets should be the Chinese. The compass, one of the four great inventions, was made of magnets.

The use of magnets in life

Magnets can generate magnetic fields and have the property of attracting ferromagnetic materials. They are mainly used in daily life for speakers, compasses, magnetic needles, magnetic toys, making motors, leather bags, electric bells, door catches, induction cookers, generators, etc.

A magnet is a kind of stone that attracts metals.

Magnets can be divided into "permanent magnets" and "non-permanent magnets". Permanent magnets can be natural products or artificially made, while non-permanent magnets only have magnetism under certain conditions.

Magnets come in many shapes, some of the most common ones are square magnets, cylindrical magnets, disc magnets, etc.
