    North pole of a bar magnet faces a closed ciruclar coil. It is oscillated rapidly along the common axis of the magnet and the coil. Determine the direction of induced current in the coil from Lenz's law.

    Statement I: The north pole of a bar magnet is moving towards a closed circular coil along its axis. As a result the direction of induced current in the front face of the coil will be clockwise. Statement II: Any incident connected with electromagnetic induction obeys Lenz's law.

    The magnets of two suspended coil galvanometer are of the same strength so that they produce identical uniform magnetic fields in the region of the coils.
