Module 3 : MAGNETIC FIELD
Lecture 15 : Biot- Savarts' Law
 
   Recap
   In this lecture you have learnt the following
The magnetic field due to a current element is determined by Biot-Savart's law.
The magnetic field due to some configurations like a line segment, a circular coil, a disk etc. was calculated
  using Biot-savart's law.
A Helmholtz coil is used to produce a uniform magnetic field over a limited region of space.
A force is exerted on a current element placed in a magnetic field.
Two current carrying circuits exert force on each other because the magnetic field due to one circuit exerts force on
  the current elements of the other circuit.
