Each piece becomes a smaller magnet with both a north and south pole, meaning monopoles cannot exist. Related Questions: Can two magnetic field lines intersect each other? Justify your answer. A freely suspended magnet always points along the north-south direction. Why? What is the neutral zone or field-free region of the magnetic field? Is there … Read more
Soft iron is used because it has high magnetic permeability, can be easily magnetized, and loses its magnetism quickly when the current is switched off. Related Questions: Can two magnetic field lines intersect each other? Justify your answer. A freely suspended magnet always points along the north-south direction. Why? What is the neutral zone or … Read more
A solenoid produces a strong magnetic field because the current in each loop adds up, creating a concentrated and uniform field inside the coil. Related Questions: Can two magnetic field lines intersect each other? Justify your answer. A freely suspended magnet always points along the north-south direction. Why? What is the neutral zone or field-free … Read more
Many species of birds and other animals, such as sea turtles, salmon, and insects, are known to navigate long distances during migration. One of the key ways they do this is by using the Earth’s magnetic field as a natural compass. This ability is known as magnetoreception, and it allows animals to detect and respond … Read more
Earth’s Magnetic Field The Earth’s magnetic field, also known as the geomagnetic field, is the magnetic field that surrounds the Earth, extending from the Earth’s interior out into space. This magnetic field is essential for life on Earth, as it protects the planet from harmful solar and cosmic radiation, and it plays a crucial role … Read more
Types of Magnetic Materials Magnetic materials can be broadly classified into three categories based on their magnetic properties: Ferromagnetic, Paramagnetic, and Diamagnetic materials. Each type of material behaves differently in the presence of a magnetic field, and these differences are due to the alignment of atomic magnetic moments within the material. 1. Ferromagnetic Materials: Definition:Ferromagnetic … Read more
Uses of Electromagnets and Temporary Magnets 1. Uses of Electromagnets: Electromagnets are temporary magnets that are created by passing an electric current through a coil of wire, often wrapped around a ferromagnetic core (such as iron). The strength of the electromagnet can be controlled by adjusting the current or the number of turns in the … Read more
Property Permanent Magnets Temporary Magnets Definition Permanent magnets are materials that retain their magnetism for a long time without needing an external magnetic field. Temporary magnets are materials that only exhibit magnetic properties when placed in a magnetic field and lose their magnetism once the field is removed. Magnetism Permanent magnets have intrinsic magnetism, meaning … Read more
Induced Magnetism: Induced magnetism refers to the temporary magnetization of a material when it is placed in a magnetic field. When a material that is not normally magnetic (such as a piece of iron or steel) is exposed to a magnetic field, it becomes magnetized and starts to act like a magnet. The magnetization of … Read more
