Question

difference between Biot Savart law and Ampere Circuital law with at least 3 points... ​

Answer 1

Explanation:

BIOT-SAVART LAW :

1. CALCULATE MAGNETIC FIELD AT A POINT DUE TO A CURRENT ELEMENT.

2. dB = ( 10^-7 i dl sin(α) ) ÷ r^2

3. The magnetic field dB perpendicular to the plane of the diagram ( i.e. either going into the plane or coming out of the plane) .

AMPERE'S CIRCUITAL LAW :

1. To calculate the magnetic field due to a given current distribution.

2. B. dl cosα = 4π×10−7 . i

3. Ampere's law is more useful under certain symmetrical conditions.

Answer 2

Answer:

Biot-Savart's law

1. This law is based on the principle of magnetism.

2. This law is valid for asymmetrical current distribution.

3. This law is the differential form of magnetic field induction B→ or magnetising force H→.

Ampere's circuital law

1. This law is based on the principle of electromagnetism.

2. This law is valid for symmetrical current distribution.

3. This law is the integral form of

B→ or H→.
