Rubber magnet, also referred as flexible magnet, is a type of magnet made by blending ferrite magnetic powder with rubber which is then calendered to produce strip, sheet, or roll. Bonded magnet can be divided into compression molded magnet, injection molded magnet, extruded magnet, and calendered magnet base on processing technology.

The magnetic flux (often denoted Φ or Φ B) through a surface is the component of the magnetic field passing through that surface. In the most general form, magnetic flux is defined as ΦB =∬AB⋅dA Φ B = ∬ A B ⋅ d A. It is the integral (sum) of all of the magnetic field .

Electromagnetic waves are composed of oscillating electric and magnetic fields. Know the formation, graphical representation, mathematical representation, intensity of electromagnetic radiation along with its speed in free space.
*T max (maximum practical operating temperature) is for reference only. The maximum practical operating temperature of any magnet is dependent on the circuit the magnet is operating in. Units of Measure. Three systems of units of measure are common: the cgs (centimeter, gram, second), SI (meter, kilogram, second), and English (inch, pound, second) systems.
The magnetotelluric (MT) method is a passive electromagnetic (EM) exploration method that measures orthogonal components of the electric and magnetic fields on the Earth's surface. The source field is naturally generated by variations in Earth's magnetic field, which provide a wide and continuous spectrum of EM field waves.
A bar magnet is a rectangular piece of an object, made up of iron, steel or any other ferromagnetic substance or ferromagnetic composite, that shows permanent magnetic properties. It has two poles, a north and a south pole such that when suspended freely, the magnet aligns itself so that the northern pole points towards the magnetic north pole ...
Introduction. If you have ever played with a really powerful magnet, you have probably noticed one problem. You have to be pretty strong to separate the magnets again! Today, we have many uses for powerful magnets, but they wouldn't be any good to us if we were not able to make them release the objects that they attract.
Mar 26, 2016 · Magnetic field through a diamagnetic material. 3. Ferromagnetic materials. The materials which are strongly attracted by a magnetic field or magnet is known as ferromagnetic material for eg: iron, steel, nickel, cobalt etc. The permeability off these materials is very very high ( ranging up to several hundred or thousand).
Magnetic Permeability Brasses are essentially nonmagnetic, a property which has gained them extensive use in electrical and electronic equipment, as well as instrumentation such as geological and survey equipment. Attractive Color Copper and gold are the only two metals with any distinctive color. In brasses, the red of copper is toned to a ...

Magnetic flux is a measurement of the total magnetic field which passes through a given area. It is a useful tool for helping describe the effects of the magnetic force on something occupying a given area. The measurement of magnetic flux is tied to the particular area chosen. We can choose to make the area any size we want and orient it in any ...
