HC Verma Solutions Vol 2 Permanent Magnets Chapter 14 is authored by Harish Chandra Verma a retired professor from IIT Kanpur. He has written many other physics books for school level, undergraduate and graduate level as well. To understand the key concepts, chapter 14 is briefly discussed below.
Permanent Magnets is the 14th Chapter in volume 2 by Harish Chandra Verma. A piece of magnetic material that retains its magnetic effect even after it is removed from an external magnetic field is called a permanent magnet. It is made of ferromagnetic materials like ferrite and alnico. These materials can be divided into magnetically soft materials and magnetically hard materials. Annealed iron is magnetically soft material. Magnetically soft materials have a low coercivity and can be magnetized but don’t tend to stay magnetized. Whereas, hard materials have high coercivity and stay magnetized. A material’s strength of magnetism is measured by its Magnetisation. Different types of permanent magnets are Ceramic, Alnico, Samarium Cobalt, Neodymium Iron Boron, Injection Molded, Flexible. Complex questions on Permanent Magnets can be solved easily with the help of HC Verma Solutions. Students of 12th grade widely use this study material to prepare for various competitive exams like IIT JEE and NEET.
This is a perfect book for students to prepare for Engineering and medical entrance exams. The Solutions discussed in Concepts of Physics Vol 2 will give students an idea on tackling difficult numerical problems in less time.
