I read your article https:\/\/www.kjmagnetics.com\/blog.asp?p=making-and-repairing-fridge-magnets<\/a> because of your email.<\/p>\n

I had hoped you would show a way to re-energize or strengthen an old magnet by using a strong magnet to increase permanent magnetization.<\/p>\n

Is that possible? Can a strong magnetic make many weaker magnets? Ferromagnetic materials, like paper clips, nails, washers, metal plates, metal sheets. How does induced magnetism of that sort work – according to the strength, size, contact area, duration of exposure to the strong magnetic field(s).<\/p>\n

If you say “Other Questions” usually ask for a subject.<\/p>\n

Thank you for the quick and effective answer.\u00a0 That article is very helpful.<\/p>\n

My impression is that each material (a weak magnet is made of something that can be magnetized) has a magnetization\/demagnetization, hysteresis, curve and there is likely information in the curve to tell what magnetic field is needed.\u00a0 The B-H curve or B-I curve tells what H field or I (current as a density) is needed.<\/p>\n

Edmund Scientific grew to great popularity when it began. Now it is just “sell for the highest price”. And it created a whole generation of scientists, engineers, technologies, inventors and explorers.\u00a0 We could do that now, but almost every retail outlet on the Internet forget “nurture your current and future market”.<\/p>\n

I suppose you think that selling “blank magnetizable materials” would reduce demand for off the shelf magnets.\u00a0 But it might create a global network of people knowledgeable in magnets.\u00a0 In computing and in all science technology engineering mathematics computing, finance government interestGroups — there are users, developers, developer and sharing networks, distributors, fabricators — whole global networks.\u00a0 It is how things get done.<\/p>\n

A teacher could involve whole classes in making magnets, using and experimenting with them.\u00a0 3D printing magnetizable materials is likely already being done, I just do not have time writing this to find them all or some.<\/p>\n

You can sell to end users, and to innovators and local experts.\u00a0 The universities, colleges, expert groups\u00a0 – concentrate certain kinds of knowledge, but they often fail at innovation and expansion of industries, because they do not have materials, suppliers, fabricator networks.<\/p>\n

You could think of “inducing knowledge of magnets and related things into global networks”. It is not passive. It can be done as a science, a profession, an industry, a technology of knowledge and growth in human networks.<\/p>\n
