Magnetic Material. A magnetic material placed in a magnetic field (H) has a magnetic induction (B), measured in teslas (T), expressed by Equation [8.44], where μ0 is the permeability of free space (4π×10−7TmA−1) and the magnetisation, (M=m/V), is the magnetic moment (m) per unit volume (V) of the material (Oberteuf, 1974).

A compass is a magnetometer used for navigation and orientation that shows direction in regards to the geographic cardinal points.For the structure of the compass, it will show the diagram called compass rose in showing the 4 main directions: East (E), South (S), West (W) and North (N). The angle increases in the clockwise position. North corresponds to 0°, so east is 90°, south is 180° and ...
Nanoparticle synthesis with coprecipitation is an easy technique, resulting in a wide-ranging size of nanoparticle synthesis. Several other methods were developed for the synthesis of more uniform-sized nanoparticles. Magnetite NPs are produced by a mixture of nanoemulsion consisting of the iron source and sodium hydroxide (NaOH) (Solans et al ...

Teach and reinforce mathematics concepts in your classroom with math posters from Really Good Stuff. Perfect for displaying on bulletin boards, black- or whiteboards, classroom doors and in math centers, these posters are well-designed reminders of important math topics, whether you're just beginning to introduce numbers to pre-Kindergartners or searching for 5th grade math posters.
The earth's surface is covered by an invisible magnetic field. The north and south poles are aligned with the earth's axis. Therefore, magnetic objects, like the needle of a compass, will align itself along the north-south axis.1 Magnetic compasses evolved from using lodestones. Lodestone is a type of magnetic mineral called magnetite.

Magnetic backing allows the user to place the whiteboard directly on a fridge. Mobile dry-erase boards are mounted on a frame and have wheels, allowing users to transport them from room to room.
The finish coat of paint also helps to protect the magnetic particles. If you want to make a magnetic chalkboard wall, don't use a mixture of magnetic paint and chalkboard paint. Paint the magnetic paint first and when its dry, sand it lightly with 000 sandpaper to get rid of any high tips of excess texture.
Recent work has demonstrated that magnetic nanocomposites composed of two magnetic materials have the ability to exhibit the desired magnetic properties, thus satisfying the need for a magnetic material with both low loss and high magnetic saturation. 5,6 5.

Afterward, the magnetic MIL-101(Fe) was subjected to calcination under a nitrogen atmosphere and magnetic porous carbon was achieved. Finally, a layer of poly(p-phenylenediamine) was coated on the magnetic porous carbon. The structure of the nanocomposite was investigated with various methods, including FT-IR spectroscopy, electron microcopies ...
electric motor - electric motor - Permanent-magnet motors: The magnetic field for a synchronous machine may be provided by using permanent magnets made of neodymium-boron-iron, samarium-cobalt, or ferrite on the rotor. In some motors, these magnets are mounted with adhesive on the surface of the rotor core such that the magnetic field is radially directed across the air gap.
