A.c. current and induced force

  1. Apr 29, 2015 #1
    when A current-carrying conductor is placed in A magnetic field due to the interference of both magnetic fields,the field is made variable so a force will be induced on the Conductor.

    so my question is, If an Ac current is passed through conductor it will have variable magnetic field will it induce a force on another object?

    Yes, it will induce a variable force.

    For example you can hear an activated ac-relay "buzzing" because two pieces of iron are attracked to each other by a variable force.

    The force will be proportional to the current at any time.
