Curl Notes & Topics for GATE EE/IES/ISRO/BARC 2019

By Vinit Kumar|Updated : September 25th, 2018

In this article, you will find the Study Notes on Curl which will cover the topics such as Introduction, Biot-savart's Law relation in respect to curl.

A divergence is a dot product between the gradient operator (the flipped triangle) and the vector field, also the curl is a cross product of the gradient operator and the vector field.

Using the Biot-Savart law for a volume current image001 we can calculate the divergence and curl of image002:


The curl of an electric field is zero. The electric field associated with a set of stationary charges has a curl of zero. In this situation, there is no magnetic field. Electric field lines curl up in opposition to a time varying magnetic field (Faraday's law of induction). Magnetic field lines curl up in response to current flow, ie. moving charges (Ampere's law, first term).

All the Best.
