what is the main advantage of the ampere s law
=> According to ampere's law the magnetic field around a current-carrying wire is proportional to the current passing through the wire.
=>The main advantage of ampere's law is its use to calculate the magnetic field of symmetric shaped current conductor. We can easily calculate the magnetic field due to a circular current conducting wire or a solenoid. Biot–Savart law is more complicated to calculate the magnetic field compared to ampere's law. Biot-Savart law uses to calculate the magnetic field for any shape.
