How are magnets made industrially
Magnets made industrially – Magnets occur in nature and are used for a lot more than just sticking stuff to the fridge. Magnets help run motors and generators and are also found in computers, microphones, and television. Scientists figured out how to make them using metal and electricity.
Magnets can stick things on, hold things together,r and make machines work. Almost every machine in our house has a magnet in it. There are only certain metals that are attracted to a magnet like iron, nickel, and cobalt. These metals can become magnets.
The production at the magnet foundry begins with the creation of the mold tray. A tray containing 4 magnet shapes is loaded into the machine, which fills with sand. The factory worker moves the pattern and smooths the surface dimpled by the machine’s lid then it is back inside.
Then the machine pumps in gases that chemically alter the sand in seconds. The sand slab is now a durable mold and these molds are made in a variety of shapes and sizes. It’s time to mix the ingredients for magnets themselves. They include cobalt, copper, nickel, sulfur, aluminum, pure iron, and titanium.
All of these metals are loaded into an electrical induction furnace. It generates a pulsating electromagnetic field that heats the metal to 3000 degrees Fahrenheit melting everything into a molten soup. The metal was then poured into the molds. As the gases of sand are highly flammable, the molds burst into flames.
The workers then slide to another part of the foundry, where they can knock down to the floor and burst them with the sledgehammers. This lets the air in, cooling the molds and allowing the gases to burn off. All the pieces are then shoveled into a bin and workers separate the metals from the sand.
The set of rings designed for use in electric motors is threaded onto a copper pipe. The ring-covered pipe is placed in a tube. Then silica sand is packed in, to hold the ring in position. Both ends of the tube are sealed with concrete. Then it is into the electrical furnace. Heat the tube until it is red.
This superheating primes the rings inside to accept an electromagnetic field, which will be delivered by the metal rod. The rod slides down the center of the copper pipe. Water keeps the pipe from melting as a low voltage high current charge is delivered to the rings inside. Then the workers break and open the seal. The whole process left the rings mildly magnetized and the rough edges are smooth away.
At this point, the magnets are pretty useless, but a machine with electromagnetic charge empowers them. Moreover, the wide array of magnets manufactured today are critical to our daily lives. This magnetic invisible power helps keep so many things running. So in this way, magnets are made industrially and are available for our daily usage.

Magnetic objects can magically attract at long distances because they generate magnetic fields that extend invisibly out beyond the object. Electricity and magnetism are just two sides of the same coin, moreover, they can be transformed into each other. The magnetic field is just what an electric field turns into when an electrically charged object starts moving.
A magnet is something that attracts certain metals. It has an invisible force that pulls the metals to itself. At the microscopic level, there are lots of electrons whizzing around in the atoms and molecules that make up any solid. Moreover, the permanent magnet can only be understood as a quantum mechanical effect. The magnets come in different shapes, which can be a bar magnet, horseshoe or ring magnets, etc.

A magnet consists of two ends known as poles. One is the North and the other is the South Pole. The north pole attracts the south pole of another magnet. The attraction and repulsion of a magnet are due to an invisible field called a magnetic field. Moreover, the strength of the magnetic field is more at the ends and less at the center.
