Eddy current question

  1. Jun 19, 2014 #1
    Need to refresh my understanding on eddy current.
    Does every metal exhibit eddy current when it comes across a Mag field?
    If this is the case, then why do induction cook tops required ferrous utensils.
    A Metal detector also works on the principle of eddy current. correct?

    There is quite a lot online about eddy currents, have you tried looking it up?
    1. yes - provided the B-field changes
    2. the heat depends on resistivity as well as current
    3. yes - amongst others
