    Antimatter refers to sub-atomic particles that have properties opposite normal sub-atomic particles. ... More specifically, the sub-atomic particles of antimatter have properties opposite those of normal matter. The electrical charge of those particles is reversed.

    Water has a much dielectric constant necause water has high dipole moment. Therefore its polar nature is greater than mica.

    Water,due to its polar nature has a large dieletic constant .therefore Water molecules have very large Electric dipole movment And us forced to rotates its respond To alternates extrnal Electric field Mica on other hand is less polar than waterand hence it has low dielectric constant

    Because soft iron has high initial permeability so that magnetisation is large even for small magnetising field,low retentivity so that the magnetisation is lost as the magnetising current is switched off.

    i want to know about its retentivity permiabiloty and cervivity

    0Thank You

    Aditya Chauhan 5 years, 10 months ago

    This is because soft iron has the property of losing its magnetism(or is able to be demagnetized) very quickly. An electromagnet works in this way: when current flows through it, it becomes magnetized, and immediately current stops flowing, it loses its magnetism. Hence, soft iron cores are the ideal material for this application

    Even in absence of charge the current flown is called displacement current. Displacement current is due to the rate of change of the electric field. In cases where there is no conduction current but a time-varying electric field, only displacement current is present.

    Yaa it is The Biot Savart Law is an equation describing the magnetic field generated by a constant electric current. It relates the magnetic field to the magnitude, direction, length, and proximity of the electric current. Biot–Savart law is consistent with both Ampere's circuital law and Gauss's theorem

    For good revision; firstly read the theory of the chapter, try to understand it, make concepts such that they become easy to learn and understand and then try to solve numerical portion with using only your understanding and solve only NCERT because cbse doesn't give out of book, it only check our basic concept. When you end with a chapter then close book and try to remembering all topics and concepts you read in the chapter. This will enhance your understanding.
