Exam

In JEE Main exam, it is a significant chapter. There can be 6 to 8 questions from this chapter, a weightage of nearly 6.6%.

The exact weightage varies from year to year. This chapter comes under a broader category which can be "Magnetism" or "Modern Physics". In NEET exam, the chapter's weightage is low to moderate and there can be 6-7% of questions from this chapter.

The chapter is one of the small and easy chapter of class 12 Physics. It includes - properties of magnetic materials, magnetic dipoles, and Earth's magnetic field.

When the electric charges moves, it creates attraction or repulsion. It creates magnetic forces and fields and called magnetism. The term "magnetism and matter" talks about the way magnetic forces and matter interact.

The obtained CUEE score of candidate will be valid, but provisional candidature may be cancelled by institute. So, candidates must clear all papers before admission process.

The IELTS exam does not need any special educational eligibility. Anyone can take it, no matter what education they have. You can have finished high school, done a bachelor's degree, or have any other level of education.

The IELTS checks your English skills in Listening, Reading, Writing, and Speaking. It does not look at your educational qualifications. The exam is for people from different education backgrounds. It gives everyone a chance to show their English language ability.

The three fundamental laws of chemistry are - Law of Definite Proportions, Law of Conservation of Mass, and Law of Multiple Proportions.

The three types of chemical bonds are - ionic, metallic and covalent bonds. When the electrons transfer between the atoms, they form the Ionic bonds by producing charged ions that are attracted to each other. When atoms share electrons, covalent bonds are created. When metal atoms share a sea of delocalized electrons, metallic bonds get created.

The chemical bonds can be primary or strong bonds such as ionic, covalent, and metallic bonds. It can also be the secondary or weak bonds like hydrogen bonding, London dispersion force, and dipole interactions.

It is the bond that holds the ions, atoms or molecules to form stable substances, compounds and larger structures.
