Answer:

In physics, specifically electromagnetism, the Biot–Savart law is an equation describing the magnetic field generated by a constant electric current. It relates the magnetic field to the magnitude, direction, length, and proximity of the electric current. The Biot–Savart law is fundamental to magnetostatics, playing a role similar to that of Coulomb's law in electrostatics. When magnetostatics does not apply, the Biot–Savart law should be replaced by Jefimenko's equations. The law is valid in the magnetostatic approximation, and consistent with both Ampère's circuital law and Gauss's law for magnetism. It is named after Jean-Baptiste Biot and Félix Savart, who discovered this relationship in 1820.

Biot Savart Law Example

Number of turns n= 10.

Current 5A.

Length= 2m.

Radius = 1m.

The biot savart law statement is given by,

B = (μo / 4π) × (2πnI / r)

Then, substitute the above values in the above equation.

B = (μo / 4π) × (2 × π × 10 × 5 / 1) = 314.16 × 10-7 T.
