How megnetic field produce a current
WebThe induced current can be increased by causing larger changes in the magnetic field or by coiling the wire so that more wire is affected by the changing magnetic field. Magnetic fields Magnetic fields arise from permanent magnets and electric charges in motion. 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.
