Transition metals are located in groups IB through VIIIB on the periodic table of elements, ferrites are ferromagnetic substances and magnetization refers to the exposure of metals to a magnetic field.... Ferromagnetic substances are materials which acquire strong magnetic properties following the direction of the applied field when exposed to a magnetic field.... Magnetisation refers to the exposure of a metal to a magnetic field causing the metal to be magnetised with the level of magnetism being a function of the strength of the magnetic field (Cullity and Graham, 2009)....

The aim of the research is to investigate the behaviors of coils and magnets in a magnetic field created by the current, testing Faraday's and Lenz's laws, and testing the behavior of a transformer that uses the two laws above to produce electric current.... This research will begin with the statement that in electromagnetic induction, a current carrying wire induced a magnetic field around the wire.... Cutting the field using a magnet will result to an induced emf, which is proportional to the rate of change of the magnetic field or speed at which the field is cut....

However, if another magnetic field is introduced, the spin-up and spin-down states will be no longer equal in energy.... The energy difference introduced by applying the external magnetic field is known as the Zeeman splitting (van Geuns, 1999).... aving microscopic magnetization, protons within a magnetic field produce wobbling as they spin.... magnetic Resonance Imaging (MRI) is a state of the art imaging technology that has shown many advantages in medical imaging such as noninvasive measurement, absence of side effects, remarkable soft-tissue contrast, and an ability to acquire images in any plane....

Magnetic shielding is the process used to reduce the magnetic field in space through usage of blocks of highly permeable magnetic materials.... epending on the material and its physical properties such as size, shape, thickness, and the frequency of electromagnetic fields and even the orientation of the material vis-à-vis magnetic field, the effects of magnetic shielding can be reduced or increased.... This is because magnetic field lines are attracted into the material and kept from spreading out as they take the path offering the least resistance (Appleman and Dailey, 1974)....

Magnetic shielding, however, does not prevent a magnetic field, preventing lines of flux from traveling from the North Pole to the South Pole of a magnet.... When a shield is so thin, it becomes saturated with magnetic field lines and cannot hold any more lines of flux.... agnetic shielding is the act of reducing the electromagnetic field contained in space by blocking the area with barriers made of either conductive or magnetic material.... These objectives would be achieved by carrying out a series of experiments based on the study of magnetism and magnetic properties of different materials....

The main component of an MRI is a magnetic field which is used to stabilize the hydrogen protons and prepare them for manipulation or excitation through the introduction of electromagnetic pulses.... Diamagnetic substances react to a magnetic field by slightly repelling it; paramagnetic substances by slightly being attracted to it, and; ferromagnetic substances aligns and strongly reacts to when they come in contact with a magnetic field (see Fig....
