Some materials have a feature known as ferromagnetism. The prefix "ferro" refers to Iron‚ which is one such material. Ferromagnetic materials have the ability to "remember" the magnetic fields they have been subjected to. An atom consists of a number of negatively charged electrons‚ orbiting around a positively charged nucleus. These electrons also possess a quantity known as spin‚ which is roughly analogous to a spinning top. The combination of orbital and spin motions is called the angular momentum

Magnetic Susceptability Michael J. Horan II Abstract: The change in weight induced by a magnetic field for three solutions of complexes was recorded. The change in weight of a calibrating solution of 29.97% (W/W) of NiCl2 was recorded to calculate the apparatus constant as 5.7538. cv and cm for each solution was determined in order to calculate the number of unpaired electrons for each paramagnetic complex. Fe(NH4)2(SO4)26(H20) had 4 unpaired electrons‚ KMnO4 had zero unpaired electrons‚ and

Compasses are used by magnetic fields coming from the North and South Poles. The way magnets come together is magnetic pulls. Examples have you ever tried to push two magnets together? Usually they go to the right or left. That is because there are magnetic fields pushing off of each other. If you just lay them down next to each other they will connect because you are not putting

The field of smart materials attempts to combine the Sensor: that detects an input signal Actuator: that performs a responsive and adaptive function and the Control circuit: on as one integrated unit Actuators may be called upon to change shape‚ position‚ natural frequency‚ or mechanical characteristics in response to changes in temperature‚ electric fields‚ and/or magnetic fields.

worldwide in all forms and styles‚ but do people really know where this rice came from or all the hard labor put into producing this amazing source of food? When it is covered by a brown hull‚ rice is called paddy; rice fields are also called rice paddies‚ or paddy fields. When planting rice‚ these are some important steps you will need to know in order to have a successful crop. First‚ you have to consider the season because you have to plant rice closer to the dryer months

• Application Fields ABSTRACT “Red Tacton” gives a whole new meaning to the term “networking”. It is a new personal area networks technology which uses the surface of the human body‚ as a safe data transmission path‚ at speeds up to 10 Mbps. Red Tacton does not rely on electromagnetic or a light wave to transmit data. It makes use of weak electric fields on the surface of the body. Using a new super-sensitive photonic electric field sensor‚ it can achieve

spin of a sort in which their compass needles can point either “up” or “down” in relation to a magnetic field. Spin therefore lends itself elegantly to a new kind of binary logic of ones and zeros. The movement of spin‚ like the flow of charge‚ can also carry information among devices. One advantage of spin over charge is that spin can be easily manipulated by externally applied magnetic fields‚ a property already in use in magnetic storage technology. Another more subtle (but potentially significant)
