The answer to what is the "strongest magnet in the world" depends on whether you're talking about strongest permanent magnet or strongest electromagnet.
While the provided text snippet focuses on ferromagnetic materials like iron, nickel, and cobalt, and mentions "coil," it doesn't directly identify the strongest magnet. Therefore, a comprehensive answer requires external information.
Here's a breakdown:
-
Strongest Permanent Magnet: The strongest permanent magnets available today are made from rare-earth elements, primarily Neodymium (NdFeB) magnets. These magnets offer the highest magnetic field strength for their size and are widely used in various applications.
-
Strongest Electromagnet: Electromagnets can achieve significantly higher magnetic field strengths than permanent magnets, but they require a continuous power supply. The strongest electromagnets are typically found in research settings. As of my last update, some of the world's most powerful electromagnets are at the National High Magnetic Field Laboratory (MagLab). They utilize superconducting materials to achieve incredibly high magnetic fields. The strongest magnetic field sustained by a non-impulsed magnet is in this type of laboratory setting.
It is worth noting that the strength of a magnet is measured in Tesla (T).
