When the current in solenoid is turned off a steel core stays magnetized. The tiny atomic magnets remain lined up, even when the external field is removed. Why is that so?
Magnetic materials are substances that have the ability to create and maintain a magnetic field. This means they can attract and repel other magnetic materials and can be used to store and transfer energy.
The mystery surrounding steel core magnetization is how the steel becomes magnetized. Scientists have yet to fully understand the process and it continues to be a topic of research and debate.
Magnetic materials work by aligning their tiny atomic magnets, called domains, in the same direction. This creates a magnetic field, which can either attract or repel other magnetic materials. The strength of the magnetic field depends on the material and the number of aligned domains.
Magnetic materials have a wide range of applications, including in electronics, transportation, and industrial processes. Some common uses include hard drives, motors, generators, speakers, and magnetic resonance imaging (MRI) machines.
Scientists study magnetic materials through a variety of techniques, including measuring their magnetic properties, analyzing their crystal structure, and conducting experiments to observe how they interact with other materials. Advanced imaging techniques, such as electron microscopy, also allow for the visualization of magnetic materials at a microscopic level.
