Magnetism and spintransport in the heterostructure of Ferroelectric/ferromagnetic films
... The operation of the current generation magnetic memories is based on the control of magnetization by a magnetic field generated by a current through wires or a local magnetic field generated from current through the spin-torque transfer. These two approaches unfortunately suffer from significant en ...

How can you make the field stronger? Add more loops!!!
... 1. Transformers - Alternating current causes a changing magnetic field in a coil, called the primary - A current is then induced in the adjacent coil, called the secondary. This current is AC, also. However, the Voltage may be higher or lower depending on the ratio of turns in the primary and second ...
