Question

State Biot Savart law​

Answer 1

Answer:

The Biot-Savart law states how the value of the magnetic field at a specific point in space from one short segment of current-carrying conductor depends on each factor that influences the field. ... In addition, the magnetic field at a point depends upon how far the point is from the current element.

Answer 2

Explanation:

biot savarts law states that

dB is proportional to dl

dB is proportional to i

dB is proportional to sin of angle between r and dl

dB is inversely proportional to r²

So, dB proportional to i dl sin ∆ by r²

dB = (u°÷4π)×i dl sin ∆÷r²
