doubts

Manufacturing technology even for a simplest products is not that simple. Here You are talking about magnet.

I Hope someone will have enough time to answer your question, But I suggest to you if you rewrite your question in full details like what kind of magnet? what shape? what basic materials? and what applications?Etc.

Its a big project and its difficult to achieve success if you don't put your maximum and sincere effort,

Two solutions:

- you buy a PM and avoid manufacturing of PM which is very complex and requires an important investment or you only make the pole pieces of soft iron for a PM.

- you take a book for magnetics and design the core and the solenoid around and manufacture them.

I do not know other kinds of magnets.

"how to manufacture a magnet" makes as much sense as "how to shave a hairless goat"

Try Wiki

They will give you a good start.

By magnetizing a ferrous metal alloy.

One of the ways is to stroke some magnetically-attracted steel with another magnet.

Neodymium rare earth magnets are the strongest permanent magnets. These neodymium magnets are manufactured to N42 grade or better, giving the best trade-off of strength vs price for both educational & industrial applications. North & south poles are through the flat surfaces. Other axes of magnetization are available on special order.

You actually can manufacture a magnet. You make a powder of a magnet, as fine as possible, or maybe make a fluid of that powder, so that the fluid is fine as possible.

You take two kind of explosives, the one which explodes from the inside, the other from the outside. Both explosives must explode at the same time, for example both will explode in 10 seconds. You can adjust the speed of the explosives with metall powders, like aluminium or coppar or whatever, to slow down the time. then you press the two explosives together gently, and when you have a kind a stone like stuff, you make a hole inside it, and fill it with something what could heat it up,like phosfor, when ignited, so that the stone start to burn slowly, but the whole process must take place in a sort of a very strong chamber, wherein a big explosion can take place, without the chamber exploding as well, or you used a kind of "hammer" with the same explosive, and hit the powder magnet as hard as possible, you will have what you asked for. very little explosive is enough, if you have counted the right formula, of the explosive time for both explosives.Remember, the explosive will only explode by a hard hit, vibration, or powerful electrical power hit, but not on it´s own, will only burn for a long time, but if you touch it, it will explode with a force of a nuclear rocket.

"You actually can manufacture a magnet. You make a powder of a magnet"

You are a real piece of work. I normally don't get personal, but, you have no clue.

Or maybe you are just so flaming intelligent that I can't understand your lunatic ravings.

"will explode with a force of a nuclear rocket"?

You again.. The answere is yes. Exactly with the force of a nuclear rocket, you are absolutelly correct! If you don´t believe me, try it. You make the explosive as i have explained. You press it in a glasfiber tube, and make it look like a cigarett. You ignite the phosfor inside it with a 12 Volt/Watt battery, and wait until it´s hot. Now you jump on it, or just kick it hard. the explosion will create shockwave, about 1 feet over the ground, a very visible and powerful force, and sound as well, and you will learn to fly, about 100 meters in the air, but you will survive.

Sorry, you're right. I tried it. It works great. Didn't even hurt.

Never again will I doubt you.
