What is the difference between Biot- Savart Law and Ampere's Law ? both have same result in application . than what is the basic difference between them.
The Biot-savart law is a fundamental law in electromagnetism that describes the magnetic field produced by a steady current in a wire. It states that the magnetic field at a point is directly proportional to the current, the length of the wire, and the sine of the angle between the current and the line connecting the point to the wire.
While both laws describe the relationship between magnetic fields and currents, the Biot-savart law is used to calculate the magnetic field produced by a specific current-carrying wire, while Ampere's law is used to determine the magnetic field around a closed loop of current.
The Biot-savart law is an important tool in understanding and predicting the behavior of magnetic fields in various situations. It has applications in fields such as electrical engineering, physics, and astronomy.
No, the Biot-savart law only applies to steady currents. For a moving charge, the magnetic field is described by the Lorentz force law, which takes into account the velocity of the charge.
Ampere's law allows us to calculate the magnetic field around a closed loop of current by integrating the magnetic field contributions from each segment of the loop. This makes it a powerful tool in analyzing the behavior of magnetic fields in more complex systems.
