What material is used in electro magnets?
The magnetic field in an electromagnet is actually produced by the coil of wires with a current running through it. However certain materials, termed 'ferromagnetic' materials concentrate the magnetic flux when a rod of the material is placed within the coil (termed the 'magnetic core'). The most common of materials used for this have been iron based.
Is beta decay affected by Aluminum?
If you have a material that emitts Beta particles there is nothing that will effect that process. However, once the Betas are emitted you can block them with Aluminum or most anything else. How many you block will depend on how fast the Betas are going and how thick your blocking material is.
Where does areas most affected by typhoon in the Philippines?
the most affected area in the phillipines is the iligan city
Which parts were most affected by cyclones in South Asia?
Bangladesh were most affected by cyclones in south asia
What will happen to a radioactive material when it is heated and at what point will it burn out completely?
Just like any other material, it gets warmer, most likely expands, and may transition from solid to liquid and/or from liquid to gas. If it's already in the gaseous state, then its pressure increases. Its rate of radioactive decay is not affected.
Is mutual flux in transformer constant for all loads?
The flux is set by the voltage applied to the transformer. In most applications, the voltage is constant, and therefore the flux is constant also.
What is proximity effect in transmission line?
The current distribution in a conductor is affected by magnetic flux produced by current flowing in any adjacent conductors as well as by magnetic flux produced by current flowing in the conductor itself. This generally causes the RF to DC resistance ratio to be higher than it would be with only simple skin effect. This effect is very important in radio frequency coils, transmission lines, and most other circumstances where radio frequency currents flow simultaneously in adjacent conductors. It is known as the conductor proximity effect.
How the losses will reduce if you keep the flux density in high level in power transformer?
The flux density is set at the most the core material can stand, which for standard laminated transformer iron is around 1 Weber per square metre. Based on that and the cross-section area of the core, the volts per turn figure is calculated for both the primary and the secondary winding. If the operating voltage stays constant, so will the flux density and the iron losses.
Why is a electromagnet not a permanent magnet?
An electromagnet only retains major magnetic properties when a current is being run through it.AnswerWhether a material makes a permanent or temporary magnet depends on the nature of the ferromagnetic material involved. For example a coil with a steel core will retain much of its magnetic flux density when the current is switched off, whereas a coil with an iron core will lose most of its magnetic flux density when the current is switched off.
What is welding flux?
The term flux means to clean. Not all welding processes use a flux. Stick welding electrodes contain fluxing agents. MIG hard wire doesn't but flux-cored MIG wire does. TIG does not as the rods are bare. Most brazing applications require flux. Gas welding usually doesn't except for certain metals.
Can the magnetism of the earth keep us on the earth like gravity?
No. The material that people and most other objects are made of is not strongly affected by magnetic fields.
Can you do Welding Operation without flux?
Yes .... but most welds will not be as good as those using flux. SMAW with bare electrodes produces poor results. GTAW and GMAW are done without flux when an inert gas is used to protect the puddle. Some Oxy-fuel welding can be done with out it. In most applications flux is used not only to protect the molten puddle but also add ingredients to the weld.
Who is affected the most with this virus?
i think pregnant woman is affected the most
What countries are most affected by tsunamis?
Japan is a country that is most affected by them
Where is it possible to view a number line?
Number lines can be viewed in most math textbooks, or any math related material. These can be found in bookstores, schools, and public libraries. Number lines can also be viewed in a web search.
How do you build a flux compression generator?
The most common flux generator is constructed from an aluminum cylinder. The end is coiled with copper and reinforced with wider selinod. The mechanism then creates an electromagnetic field.
What group was most affected by the sedition act?
The Democratic Republicans were most affected
