Eddy current facts for kids

Kids Encyclopedia Facts

An eddy current can be made when you have a solenoid (coil of wire), in which there is a soft iron core. When you connect the solenoid to an AC power source, metal objects held above the cross sectional area of the solenoid are repelled due to Lenz's Law.

Images for kids

  • Linear motor field

    A cross section through a linear motor placed above a thick aluminium slab. As the linear induction motor's field pattern sweeps to the left, eddy currents are left behind in the metal and this causes the field lines to lean.

  • EI-transformer core interleaved with flux paths

    E-I transformer laminations showing flux paths. The effect of the gap where the laminations are butted together can be mitigated by alternating pairs of E laminations with pairs of I laminations, providing a path for the magnetic flux around the gap.
