Magnetic field due to semi infinite wire
Web22. A typical current in a lightning bolt is 10 4 A. Estimate the magnetic field 1 m from the bolt. 23. The magnitude of the magnetic field 50 cm from a long, thin, straight wire is 8.0 μT. What is the current through the long wire? 24. A transmission line strung 7.0 m above the ground carries a current of 500 A. WebDec 25, 2024 · Thus, there must be a buildup of charge at the ends of the wire, which constitutes an increasing electric field. If you look at Ampere's law with Maxwell's modification, the changing electric field must be accounted for in the curl of the magnetic field. This is not the case for an infinite wire, where there is no charge build up. …

WebA wire with current i = 3. 0 0 A is shown in the figure. Two semi-infinite straight sections, both tangent to the same circle, are connected by an circular arc that has a central angle θ and runs along the circumference of the circle. The arc and the two straight sections all lie in the same plane. WebThe magnetic field due to a current in semi-infinite straight wire is as follows: B s t r a i g h t = μ 0 i 4 π R According to the right hand rule, both wires produce a magnetic field that is pointing out of the page. The magnetic field due to the current in a circular arc of the wire is: B a r c = μ 0 i ∅ 4 π R
