Some iron (or an ore, alloy, or other material) that's its component atoms so ordered which the material exhibits properties of magnetism, like attracting other iron-containing objects or aligning itself in an external magnetic flux

To imagine a magnet, denotes that evil influences will draw you from the road of honor. A woman might be luring one to ruin. Female, this dream foretells that protection and wealth will be showered upon her.

Magnetic sheets which might be inserted with your printer can be found at office supply stores. These stores also carry magnetic sheets which can be placed on business cards. It may easily be cut to be able to sizes.

These are generally strips of flexible magnetic material that affix to the graphic or fabric panels and invite the panels to stay towards the channel bars. There is a & B polarity magnets. On some pop-up booths the A magnets affix to the channel bar, and also the B magnets affix to the panel

Magnetic energy has been seen as to enhance restful sleep, relieve aches and discomforts, reduce anxiety, stimulate circulation, provide increased energy and balance, and assist the body more effectively restore and repair itself. A large wide variety of magnetic products available.

"Some of the disadvantages of Permanent magnet DC motor are as follows:   1. Permanent magnets cannot produce as high a flux density as an externally supplied shunt field.   2. PMDC motors run the risk of demagnetization. The armature current IA in a dc machine produces a magnetic field of its own. The armature mmf subtracts from the mmf of the poles under some portions of pole faces and adds to the mmf under other portions of the pole faces, reducing the overall net flux in the machine.   3. In a PMDC machine the pole flux is just the residual flux in the permanent magnets. If armature current becomes very large, there is some risk that armature mmf may demagnetize the poles, permanently reducing and reorienting the residual flux in them.   4. Demagnetizing may also be caused by the excessive heating which can occur during prolonged periods of overload.   <a href=http://in.docsity.com/en-docs/DC_Motors-Electro_Mechanical_Systems-Lecture_Slides_>DC Motors</a>"
