Where to find free neodymium magnets

Magnet use helps to hold the tablecloth in one place when having an outdoor party. The magnets prevent the wind from blowing them away together with the items placed on the table.

Use of magnets rarely damages the table with the use of tape residue or holes. In answering the question where to find neodymium magnets in household items, audio speakers are probably the most likely option.

At home, you have many speakers all over including TV speakers, radio speakers, microphones, earphones, woofer and more. So why do speakers have magnets? The majority of speakers are designed with some permanent magnet that interacts with a coil of wire. The audio signal is supposed to flow through the wire and then moves the speaker. The speaker moves the air, making a sound. So, which speakers at home that are designed with neodymium magnet? This may surprise you like the small size counts.

While the huge type such as subwoofer may use a ceramic magnet, the tiny ear-buds that you use on your mp3 or smartphone are likely to use neodymium magnets. Normally, the speakers are controlled by an electric current and two magnets.

A mobile electromagnetic coil is suspended near a fixed magnet, and an electric current is pushed via the coil very quickly. The coil is attracted to the magnet after getting charged and gets repelled again creating vibrations that are amplified to become music to your ears.

What is the difference between neodymium magnets and ceramic magnets? Ceramic magnets are way more cheaply compared to neodymium, making them a popular choice for consumer applications. But there is no substitution for neodymium magnets when it comes to commercial applications. Ceramic magnets are less strong magnetically and not like neodymium magnets which are stronger and harder.

Ceramic magnets are brittle, and that makes them susceptible to damage. They easily break if dropped on the ground. On the other hand, neodymium magnets are physically harder and rarely change when exposed to stressful conditions. Also, when dropped, you will never see them break as ceramic magnets do. The only advantage ceramic magnet has over neodymium magnet is resistance to corrosion.

I have a photo of one of these holding up a 10 pound weight without breaking a sweat. Would probably do What you probably don't have are Torx bits and possibly "Tamper Proof Torx" bits.

Torx look like stars. In an emergency, you can sometimes use a hex bit and wedge it in there. Torx bit sets are everywhere, just search around and you'll find them. With the bits, get a driver. What you'll end up with is a magnet that won't break a sweat holding a 10 weight in non-optimal position, as shown here:. It would hold more if it were horizontal instead of vertical It won't hold 20 this way, but I'll bet it would hold Torx look like. My plan for data destruction! If you have a child An X-Acto knife also comes in handy.

Pliers, or vice grips, or channel lock pliers to pull the magnet out. DAS: Note to insert photo of various tools What you'll end up with is a magnet that won't break a sweat holding a 10 weight in non-optimal position, as shown here: It would hold more if it were horizontal instead of vertical Meet the drives! Pictured below are 4 hard drives of various manufacturers and vintages.

That was another lifetime ago - all these drives date from somewhere around to and are long past their useful life.

To begin, follow these general rules: "If you see a screw, remove it. Cut around it with the x-acto or cut an X shape and peel things back. Most screws will be pretty obvious.

Some will almost always be hidden. Hold the drive at an angle and feel with your finger, many times you will feel or see a small depression where the label covers a screw. Here are a few examples, I circled the hidden screws in red: And a few more examples: Here are all the screws I pulled out, also circled in red: Once you have all the screws out, start to pry up on a corner and see if the lid pops off.
