Question

What are the four magnetic materials?

Answer 1

Hint: In this question, we need to state four magnetic materials. First, we will understand the concept of magnetic materials. Magnetic materials are defined as materials that are attracted by a magnet.

Complete step by step solution:
Let us discuss the various magnetic materials that exist in nature. We can say that the materials like Iron, cobalt, nickel, Gadolinium, Dysprosium, Terbium, and various rare-earth metal alloys are examples of magnetic metals. Such magnetic materials will be classified into three types: permanent magnets, electromagnets, and neodymium magnets. Whenever we discuss magnets, we usually refer to permanent magnets. Here, we can say that magnetic materials can be magnetized, or magnetic materials can be turned into magnets.

Therefore, the materials like Iron, cobalt, nickel, and Gadolinium are magnetic materials.

Additional Information: The earliest magnets discovered were lodestones, which are hard block stones. Shepherd Magnes is thought to have found it accidentally during feeding his sheep. Magnetite is an iron mineral found in lodestone, known as a natural magnet. Also, we can say that Magnets come in a variety of forms, such as bar magnets, horseshoe magnets, disc magnets, and so on. Like magnetic poles repel each other, whereas unlike magnetic poles attract. That means, every two magnets have the characteristics of attraction and repulsion.

Note: Many students generally know only three magnetic materials like Iron, cobalt, and nickel. But apart from that, there are so many magnetic materials present in the world.
