How are slate and shale alike?
Dark Colour, Clay mineral composition (Kaolanite), Laminations of minerals
Is shale resistant to erosion?
No, all sedimentary rocks can be eroded and shale is characterised by very fine laminations. Hence the shale breaks easily along these planes of weakness and is therefore easily eroded.
Why is your strip light buzzing?
If your terminology of strip lighting is fluorescent lighting, the buzzing will be the ballast. The laminations are becoming loose and that is the 60 Hz frequency that you hear when the lamination plates in the ballast hit together.
What is the name of the chemical found in electric transformer?
High power transformers used to contain PCP's, but modern transformers contain mineral oil because it is less environmentally sensitive.
Can eddy current only exist in conductive or nonconductive materials?
'Eddy currents' are a circulating currents set up as a result of voltages induced into a metal component which not intended to carry current. For example, eddy currents are induced into the silicon-steel core of a transformer due to voltages induced into the core by the changing currents in the transformer's windings. Eddy currents are unavoidable, although steps can be taken to minimise them -in the case of a transformer's core, by manufacturing the core from laminations. Eddy currents generally have no useful function, but represent energy losses. To answer your question directly, eddy currents can only exist in conducting materials.
The reasons for using laminations in the core of some electromegnets is to?
To decrease eddy currents in the core which result in heating / extra losses. The thinner the laminations, the more effective this is.
Were laminations used in World War 2?
Yes
Why laminations are used for iron parts of a dc machine?
Laminations minimize eddy currents, or current flow across the iron parts. This is one method to minimze stray losses.
How do you make handmade carton strong enough for a box?
If your using card stock, or cardboard, the key is laminations & glue. (don't use flexible glues, use glues like plastic resin glues that dry hard) also depending on size: larger, more laminations. Smaller less laminations. If you want it as sturdy as a wood box, again more laminations, and you must glue both sides of all interior cardboards. Good-Luck

What is CRGO?
Cold-Rolled Grain Oriented silicon steel. Used in transformer core laminations. whatisCRNO? in transformers
Lamination of the iron core is used to reduce eddy current due to?
The laminations on the core of a transformer are actually insulated from each other. This means that there is no circuit for current to flow, but since the laminations are stacked in an alternating orientation, there is magnetic coupling. If the core were one piece, or the laminations where allowed to touch each other electrically, there would be current flow, i.e. eddy current flow, because the core would represent a one turn secondary that is shorted. This means low voltage, but high current capacity. This means power loss, and degradation of Q and efficiency in the transformer.
What prevents transformer laminationsfrom shorting to the adjacent laminations?
You need to prevent transformer laminations from shorting to each other because, otherwise, there would be eddy currents that affect the Q of the transformer, effectively impacting its efficiency. They would also cause the transformer to run hot. If the laminations were not insulated from each other, they would constitute a one-turn shorted winding, with high internal current. Usually, the laminations, in the shape of an E, are inserted into the windings alternately from each end, enhancing magnetic coupling while not causing the one-turn short. This is the same issue involving routing a conductor through a hole in a panel - the hole must be relieved, or slotted, to prevent eddy current, or (better) both conductors must be routed through the same hole, balancing the current, resulting in no eddy current.
Why lamination of different length of leaf springs use in automobiles?
because the stress developed at centre is maximum that is why there is no need for full length progressive laminations.
Why does a transformer make a sound when it is running?
The alternating magnetic fields cause attraction/repulsion vibrations within the windings and core laminations which manifest themselves as sound.
Where can one purchase shipping crates?
One could purchase crates from Laminations. They have a website that one can purchase from and one of the items that they sell are crates that are made for shipping.
What are the essential parts of a transformer?
A magnetic core made of iron laminations, forming a closed loop, and two or more coils of copper wire wound to intersect the core.
