Magnetic field of wire formula
WebFirstly, let's define the equation that allows us to calculate the magnetic field generated by a current-carrying wire. It is given as B = μ 0 2 π I r, where B is the magnitude of the magnetic field measured in teslas T, μ 0 is the permeability of free space given by a value of 4 π × 10 − 7 H m where H denotes henrys,

It grows linearly with the radius r … WebMagnetic Field between Two Loops Two loops of wire carry the same current of 10 mA, but flow in opposite directions as seen in Figure 12.13. One loop is measured to have a radius of R = 50 cm while the other loop has a radius of 2 R = 100 cm.
WebThe formula therefore for calculating the “Magnetic Field Strength”, H sometimes called “Magnetising Force” of a long straight current carrying conductor is derived from the current flowing through it and the distance from it. Magnetic Field Strength for Electromagnets Where: H – is the strength of the magnetic field in ampere-turns/metre, At/m WebThe magnetic field of an infinitely long straight wire can be obtained by applying Ampere's law. The expression for the magnetic field is. Show. For a current I = Amperes and. radial distance r = m, the magnetic field is. …
