Concise Physics Class 9 ICSE Solutions for Chapter 10 - Magnetism
Q1. What do you Mean by Lodestone?
Ans: Lodestone is recognized as the first magnet discovered. It is an ore of iron oxide (Fe3O4) found in huge amounts in Magnesia, in Asia Minor.
The scientists proposed that lodestone possess two properties:
Small iron pieces are attracted by it.
When it is put off at will, it makes a path to go on in a definite direction.
Q2. What is Your Idea About the ‘Artificial Magnet’?
Ans: Artificial magnet is known as a magnetized section of iron or any supplementary magnetic material. There are requirements for artificial magnets which are described below:
Artificial magnets can be stronger as compared to the natural magnets because we can make artificial magnets stronger.
Artificial magnets can be formed with proper shape and size as required. But, in the case of natural magnets, they are never in a definite shape and size.
Q3. What are the Basic Learnings Provided by Vedantu?
Ans: Vedantu is offering the study program on the subjects, which are Physics, Chemistry, Mathematics, and Biology.
The concept, along with precise question and answer sets can be helpful to our students in these subjects. We are covering all syllabuses for the CBSE as well as the ICSE board.
Q4. What is Your Perception of the Term Magnetic Field Lines?
Ans: The term ‘magnetic field lines’ can be explained as the continuous curves in a magnetic field to the extent that the direction of the magnetic field at that point can be obtained by drawing a tangent at any point of the curve.
