A.c. current and induced force

[BasilBassam]

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.
