Bullish - Video. Magnetism Experiments: Bar Magnets, Iron Filings & Compass Science. Posted: April 8, 2025 | Last updated: April 8, 2025. The video explains the concepts of magnetic, electric, and ...

At room temperature, a pure bar of neodymium wouldn’t be a magnet at all. In fact, it would need to be chilled to below 20 K to have any magnetic properties. ... To make iron nitride magnets, ...

New research published in Physical Review Letters suggests that superconducting magnets used in dark matter detection ...

The creation of magnets involves a fascinating process that blends science and precision. It all begins with raw materials like iron, nickel, or cobalt, which are combined in specific ratios to ...

As you may recall from Physics 101, a changing magnetic field (like when you slide a bar magnet through a copper coil) induces an electric current. At planetary scale, Earth’s magnetic field induces ...

Cutting a bar magnet in half won't get rid of its poles. It'll just produce two magnets, each with a north pole that will be attracted to the other magnet's south pole, and vice versa. It's this ...

The Earth's magnetic field is analogous to a bar magnet, with north and south magnetic poles extending far into space. Historically, magnetic rocks, known as lodestone or magnetite, were ...

Before this neodymium-iron-boron magnet came along in 1984, electric motors, generators, audio speakers, hard-disk drives, and the like had to make do with pricey samarium-cobalt magnets.

The global neodymium-iron-boron magnet market size reached US$ 13.6 Billion in 2021. Looking forward, the publisher expects the market to reach US$ 21.1 Billion by 2027, ...

After training the program on researchers’ previous iron magnet attempts (which varied parameters like heat and fabrication time), BOXVIA began to identify weaknesses and potential improvement.
