Question

please explain the above formula in detail.
​

Answer 1

Friend here is ur answer

When a bar magnet is bend into the shape of a horseshoe, the magnetic field between the poles is nearly uniform and usually quite strong. B = μ0I/(2πr). This equation is derived from one of Maxwell's equations called Ampere's law. Your fingers curl into the direction of the magnetic field produced by the current.

Some other knowledge is given below ✍

What is the formula for magnetism?

The combination of electric and magnetic forces on a charged object is known as the Lorentz force . This formula for the magnetic force on a current carrying wire is the basis for the experiment that was used to define the ampère from 1948 to 2019.

introduction.

FB ℓ = μ0I2 2πr(1 m) = 2π(1 m)

Is B magnetic field?

A is still used for vector potential, B for magnetic field (or magnetic induction or flux density, depending who you ask), H for magnetic intensity, etc.Feb 12, 2012

Answer 2

It's ampere's law applied to a straight wire. (I think you can also derive it from Biot savart) Its used to find the magnetic field due to a straight wire w/current.
