What protection can be placed around a magnet when being used in an autoclave environment?This depends - if the autoclave is only going to pull to the milliTorr level, then regular magnet materials will hold up. Bonded magnets will lose 30 to 40% of their output and will outgas, but after initial...
Do all grades of Nd-Fe-B material still need to be coated/plated?
Nd-Fe-B magnets have improved dramatically over the last 10 years. But they still contain iron and other reactive phases, and will rust. Nd-Fe-B is a blended powder before it is pressed into a magnet. The better the powder is mixed,...

Shaded-pole motors are the original type of AC single-phase induction motor. A shaded-pole motor is basically a small squirrel-cage motor in which the auxiliary winding is composed of a copper ring or bar surrounding a portion of each pole. This auxiliary single-turn winding is called a shading...
Shaded-pole synchronous motors are a class of AC motor.
Like a shaded pole induction motor, they use field coils with additional copper shading coils (see the illustration) to produce a weakly rotating magnetic field. But unlike a shaded pole induction motor (which uses a squirrel cage rotor), the...
How can I make permanent magnets with Iron?
You can build a electro-magnetizer : Make a huge coil with thousands of turns of thick copper wire, and rig up a bunch of large capacitors (at least totalling 500000 microfarad) to charge from a battery (with some charge control ) and discharge...
What are some applications of permanent magnets?
Scientists use four basic ways to categorize magnets, based on how their magnetic force is used.
These applications are the simplest use of magnets. A simple refrigerator magnet is a perfect example-a picture or slogan on a small piece of laminated...
How does one make "homemade" permanent magnets?
I would like to try and manufacture some permanent magnets for a project in my welding class, and I wasn't sure if it would be possible for me to do so. I suppose a good addition to this question is "What is the process for making permanent...
What element is used to make permanent magnets?
There are several categories of permanent magnets.
Ordinary bar magnets are made of Iron, usually relatively soft Iron.
The metals in Alnico magnets are indicated by the pairs of letters making up the name, Aluminum, Nickel and Cobalt. Nickel...
Starting methods of synchronous motors
Above a certain size, synchronous motors are not self-starting motors. This property is due to the inertia of the rotor; it cannot instantly follow the rotation of the magnetic field of the stator. Since a synchronous motor produces no inherent average torque...
Applications and advantages of Synchronous motorUse as synchronous condenser
V-curve of a synchronous machineBy varying the excitation of a synchronous motor, it can be made to operate at lagging, leading and unity power factor. Excitation at which the power factor is unity is termed normal...
A synchronous electric motor is an AC motor in which, at steady state, the rotation of the shaft is synchronized with the frequency of the supply current; the rotation period is exactly equal to an integral number of AC cycles. Synchronous motors contain multiphase AC electromagnets on the stator...
Yes, permanent magnets become weaker over time, because it is more energetically favorable for a ferromagnet to be subdivided into many domains giving a net magnetization of zero. The timescale of this process will depend on the operating temperature, and whether you can observe this...
If you're looking for magnetic field generation rather than something that has energy stored in the form of magnetic field, you should be looking at electromagnets instead of materials that store magnetic fields.
The design that has been able to produce stronger magnetic fields than any other...
DC motorsBrushed DC motors are constructed with wound rotors and either wound or permanent-magnet stators.
Wound statorsThe field coils have traditionally existed in four basic formats: separately excited (sepex), series-wound, shunt-wound, and a combination of the latter two;...
Synchronous motors fall under the more general category of synchronous machines which also includes the synchronous generator. Generator action will be observed if the field poles are "driven ahead of the resultant air-gap flux by the forward motion of the prime mover". Motor action will be...
The following graphics illustrate a simple, two-pole, brushed, DC motor.
