## Use Ampere’s circuital law to derive an expression for the magnetic field due to a long straight wire In this article, we will derive an expression for the magnetic field due to the long straight current-carrying conductor using Ampere’s circuital law. So without talking more, let’s start… AMPERE’S CIRCUITAL LAW: A SNAPSHOT Let’s recall what Ampere’s circuital law…

## Ampere’s circuital law | statement, applications, explanation and proof, class -12 AMPERE’S CIRCUITAL LAW OVERVIEW In classical electromagnetism, Ampère’s circuital law relates the integrated magnetic field around a closed loop to the electric current passing through that loop. In 1861, James Clerk Maxwell derived it using hydrodynamics in his published paper…

## Similarities and differences between Biot-Savart Law and coulomb’s law, class 12 SIMILARITIES AND DIFFERENCE BETWEEN BIOT-SAVART LAW AND COULOMB’S LAW In this article, we are going to discuss about similarities and differences between Biot-Savart Law and coulomb’s law. So let’s start… Both laws are used to measure the different quantities, one…

## Derive an expression for magnetic field on the axis of a circular current carrying loop, Class 12 In this article we are going to derive an expression for magnetic field on the axis of circular current carrying loop. So without talking so much let’s gets started… MAGNETIC FIELD ON THE AXIS OF A CIRCULAR CURRENT CARRYING LOOP…

## Derive an expression for magnetic field due to a straight current carrying conductor (finitely and infinitely long) We know that when electric current flows through the straight current-carrying conductor then it creates a magnetic field that encircles the conductor as shown below: Learn more about magnetic field due to straight current-carrying conductor.  So it is okay that…

## Magnetic field due to a straight current-carrying conductor MAGNETIC FIELD DUE TO STRAIGHT CURRENT-CARRYING CONDUCTOR INTRODUCTION We know that static electric charges create an electric field around itself whose magnitude depends on the value of charge and the distance of the point where we want to find the…

## Biot-Savart Law | statement and applications | Biot-Savart Law formula derivation class 12 BIOT-SAVART LAW INTRODUCTION We have seen that mass produces a gravitational field and also interacts with that field. electric charges produce an electric field and they also interact with that field. Moving charges i.e electric current produces a magnetic field…

## Oersted’s law | Oersted’s experiment class 12. ØRSTED’S LAW AND OERSTED’S EXPERIMENT INTRODUCTION We know that when an electric charge moves with a constant acceleration then it creates an electric field as well as a magnetic field. But how do we know that it creates a magnetic…

## Magnetic field and, properties of magnetic field lines, class 12. MAGNETIC FIELD AND MAGNETIC FIELD LINES INTRODUCTION Till now, we have studied various topics of current electricity through previous articles. In current electricity, we have mainly dealt with the kinematics and internal effect of the moving charges. Such as electric current,…
