Magnetic Effect of Current

Image
  In this article, we will study the topic   Electromagnet , How electric motors work? and Law of Electromagnetic Induction from chapter Magnetic effect of current, out of   Class 10 Science . What is Electromagnet? The electromagnet is created by magnetising the magnetic material with a strong magnetic field within the solenoid. A soft iron is one such material. Properties With the increase in electric current, the magnitude of the magnetic field also increases, and vice versa. With an increase in distance, the magnitude of the magnetic field decreases, and vice versa. Magnetic field lines are always parallel. No two lines intersect each other. Force on a current-carrying conductor in a magnetic field As per Andre Marie Ampere (1775-1836), the magnet exerts the equal and opposite force on the current carrying conductor. This is illustrated in the below diagram. In the diagram, the rod experiences the force when it is placed in a magnetic field in a perpendicular directio...

What are conductors and insulators?

Image
CONDUCTORS : Conductors are the device having a conductivity greater than 10 3  s/cm. Basically, electrical properties of any material depend on the electronic population inside an atom as conduction is the result of the motion of electrons within the bands. In case of conductors, the conduction band is almost full and conduction band overlaps with valence band hence there us full conduction or full flow of electron from one band to another. Even at low temperature, it results in higher conductivity. For more notes for Class 12 Physics visit  www.takshilalearning.com . SEMICONDUCTORS : Semiconductors have conductivity for silicon (it can range from 10 -5 S/cm to 10 3 S/cm). Their conduction is almost empty and valence band is almost full, the energy gap between the conduction band and valence band is around 1eV. Their no such elements like semiconductors occur naturally they are formed by doping in insulators. At the high temperature, they start conducting. INSULATORS : In cas...
