The paramagnetic variant of this effect can be seen in BSCCO if it is under a weak magnetic field. In addition to the Wohlleben effect, this effect was first described in a set of equations relating the time derivative of the current to electric field and the curl of the current to magnetic field.

The paramagnetic variant of this effect can be seen in BSCCO if it is under a weak magnetic field. In addition to the Wohlleben effect, this effect was first described in a set of equations relating the time derivative of the current to electric field and the curl of the current to magnetic field.  Applying Ampere's law to those equations yields another equation which relates the Laplacian of the magnetic field to the magnetic field multiplied by the reciprocal of a characteristic length, lambda.  In addition to being described by the London equations, this effect makes materials have a magnetic susceptibility of negative 1, making them perfectly diamagnetic. It can be observed by a magnet floating above a superconductor. For 10 points, name this effect where a superconductor expels all external magnetic fields.
