How megnetic field produce a current
Web20 feb. 2024 · Find the current in a long straight wire that would produce a magnetic field twice the strength of the Earth’s at a distance of 5.0 cm from the wire. Strategy: The Earth’s field is about 5.0 × 10 − 5 T, and so here B due to the wire is taken to be 1.0 × 10 − 4 T. WebThe magnetic field generated around a straight length of current-carrying wire is very weak even with a high current passing through it. However, if several loops of the wire are wound together along the same axis producing a coil of wire, the resultant magnetic field will become even more concentrated and stronger than that of just a single loop.
