How does polarisation help charged objects exert force on insulators?

Unlike conductors, the electrons in insulators (non-conductors) are bound to the atoms of the insulator and cannot move around freely through the material. However, a charged object can still exert a force on a neutral insulator due to a phenomenon called polarisation. If a positively ...

This High School Physics BLOG is founded with a few aims like providing (1) content for online physics learning, (2) online physics free reading material (3) online physics High School Course notes (4) online physics lab course material (5) Online physics help in different formats (6) publishing online physics calculator & (7) online physics simulator, etc. to assist students in mastering the basics or the fundamentals by publishing quality content.

And we have come across a few miles, and we have many miles to go.

Students of different boards like ICSE, CBSE, IGCSE, GCSE, State Boards, etc. are our readers. Persons who are preparing for AP physics & other competitive examinations like UPSC, IIT JEE, NEET are also our regular readers.

The posts published here have been successful so far to clarify confusion in young minds. PhysicsTeacher.in has been selected as one of the Top 50 Physics BLOG by the panelist of feedspot.com. This makes us a member of the Top 50 Physics BLOGs.

This blog is crafted to help the readers to build a foundation for different examinations like JEE, NEET, SAT, and AP Physics. It also focuses minutely on Class 8 to 10, and class 11 and class 12 Syllabus for different boards like ICSE, CBSE, ISC, GCSE, IGCSE State, etc, specifically for Physics.


This may be equally efficient for the global K12 Physics syllabusThis BLOG is to some extent like an online physics tutor providing online physics coaching and physics notes, through regular blog posts on various topics, helping students in mastering physics fundamentals.
