WebMagnetism. (1) physical phenomenon produced by the motion of electric charge, resulting in attractive and repulsive forces between objects; (2) property of a material or object to attract other objects made out of iron, magnetite, or steel. Magnetic Poles. Two regions in a magnetic field, called magnetic north and south poles, that produce the ... WebCorrect option is B) The substances which are attracted towards a magnet are called ferro-magnetic materials Materials that can be magnetized, which are also the ones that are strongly attracted to a magnet, are called ferromagnetic (or ferrimagnetic). These include iron, nickel, cobalt, some alloys of rare-earth metals, and some naturally ...

WebBar magnets and horseshoe magnets are examples of permanent magnets. Induced magnets Unlike a permanent magnet, an induced magnet only becomes a magnet when it … WebAC magnetic fields are a result of the electricity delivered from the electrical grid. In a perfect world, the electricity should be received from and then returned to the electrical utility only through the utility’s power lines. In reality, this often doesn’t occur and can lead to elevated AC magnetic field levels within the home. how many 8ths is .75

Magnetic Field: What is it? (And Why is it Important)

Web6.6.2 Hard magnetic alloys. Hard magnetic alloys (also called magnetically hard alloys) have sufficiently high coercive force as a resistance to demagnetizing fields with coercivities exceeding 10 kA m −1. These alloys can be used as permanent magnet materials with high magnetic induction that is retained because of a strong resistance to ... WebMar 23, 2012 · by Ron Kurtus (updated 23 March 2012) Materials respond differently to the force of a magnetic field. There are three main classifications of magnetic materials. A magnet will strongly attract ferromagnetic materials, weakly attract paramagnetic materials and weakly repel diamagnetic materials. The orientation of the spin of the electrons in an ...
