WebThe magnetic-field lines from the magnet pass through the cardboard, the air, and other materials like the craft stick and straw. Materials that allow magnetic lines of force to pass through them are called nonpermeable … Web5 nov. 2024 · Zero Force When Velocity is Parallel to Magnetic Field: In the case above the magnetic force is zero because the velocity is parallel to the magnetic field lines. (21.4.7) F = q v B sin θ. If the magnetic field and the velocity are parallel (or antiparallel), then sinθ equals zero and there is no force.

WebLenz’s Law of Electromagnetic Induction. Faraday’s Law tells us that inducing a voltage into a conductor can be done by either passing it through a magnetic field, or by moving the magnetic field past the conductor and that if this conductor is part of a closed circuit, an electric current will flow. Web• Magnetic field strength And our story ends here if generator terminals are open-circuited. 5.If, however, the phase (armature) windings are connected across a load, then current will flow in each one of them. Each one of these currents will in turn produce a magnetic field. So there will be 4 magnetic fields in the air gap. One from the ...
