Can magnets be temporary?
Electromagnets are temporary magnets made of iron usually that are created by passing a current through a wire wrapped around the iron. There are also ways of making temporary magnets out of ordinary iron objects that can later be demagnetized. I am not wise in the ways of these latter type of temporary magnets.
Can a wire be wrapped around a screw clockwise or counter clockwise?
Well, it CAN be wrapped either way, but because standard screws tighten when turned clockwise:if the wire is wrapped around the screw clockwise tightening the screw will pull the wire tighter around the screwif the wire is wrapped around the screw counterclockwise tightening the screw will push the wire away from the screw making it loose and maybe even popping the wire out from under the screwSo, if you want the wire to stay secure on the screw only wrap it clockwise!
What is special about the metal Craig Wire sells?
Craig Wire sells wire and magnetic wire that can be used to make electromagnets. It is special because only certain types of wire are suitable for making electromagnets.
Where is the electromagnet the strongest?
The strongest type of electromagnets are superconducting electromagnets. Usually these superconducting electromagnets are immersed in liquid nitrogen or liquid helium to cool them to near absolute zero. === === For non-superconducting electromagnets, the strongest electromagnets would have the greatest ampere turns over a large area. The core of the magnet would be a highly ferromagnetic material, such as iron, or a mixture of a ferrite and a ceramic. Very strong electromagnets used for lifting machinery have both poles on the bottom side which will maximize the magnetic field produced. Non-superconducting electromagnets will saturate and stop producing magnetic fields at about 2 teslas or so. This is the limit of magnetic strength of ordinary electromagnets.
Where can you get acrylic yarn that goes thin and then large there is thin string wrapped around the yarn that tightens and then loosens making thin and then fat sections?
You can usually find this yarn at Joans Craft Store.
Why is plastic wrapped around metals in wire?
It prevents the wire making contact with other wires and shorting out. It protects the wire from erosion and allows the user to identify what each wires role is within the harness
What would happen if you took wires and made a long strand then wrapped them around a metal nail then finally connect them to a battery?
You would succeed in making a simple electro-magnet that uses the copper wire as a conducter for the elctricity that comes from the battery,the nail on coming in contact with the wire which is wrapped around it harnesses the elecric power being provided by the battery via the copper wire and an magnetic field around the nail is created, hence the name electro-magnet!
How do you remove hair from a tub drain?
Drain cleaner or a snake. If you use a snake, take the overflow plate off on the side of the tub above the drain and go down from there. That saves making the sharp bend if you go through the drain itself. It may be hair wrapped around the drain shut off which will come out when you remove it from the overflow tube.
What type of material is used for making temporary magnet?
An electo-magnet has an iron core wrapped round with wire coils. When electricity is passed through the coils, the iron core become magnetised, until the electricity is switched off.
How are electro magnets used in cranes?
Cranes with electromagnetic lift are known as electromagnetic cranes. Such cranes are used widely in lifting and moving scrap metal. Even in a production line of many products, electromagnetic cranes are used to lift and move the metal objects. Electromagnetic cranes are particularly simple and have many advantages over other lifting tools. They are both faster and easier to work with.
Electromagnets are generally weaker than permanent magnets?
Depends on the size. One good example of a powerful electromagnet is the one used to lift cars at junk yards. Permanent magnets are not used for that due to the sheer power needed to lift cars. Also, electromagnets can be turned ON and OFF making them useful in picking up and then dropping the junk cars as needed. Another big example of electromagnets are the ones used on power generators to generate electric power.
Definition of a monetary pass through?
You are a non profit and you receive money on behalf of a profit making company. You then turn around and write a check to the profit making company for the exact amount you got. Is that not a monetary pass through?
