Hi.
This bobbin coil has no core. If we pass a 10 Ampere AC conducting wire into/trough it as core, will there be any AC voltage reading at the coil terminals ?

Through the center is not an ideal configuration, the flux from the current carrying wire is in the same direction as the coil, it will induce very little voltage.

Hi. Thanks.




Are you sure ? the coil in post #1 is not toroidal as

"..Yes, somewhere between almost nothing and a lot..."


For a wire to experience magnetic force due to current thru it, that wire has to be perpendicular to the magnetic field lines. The misalignments won't be perfect (parallel to B fields) so some force will felt between the wires that depends on the physical spacing, construction and frequency.
