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.
What is the significance of CORE?
A transformer's windings are pre-wound around insulated 'formers' or tubes of circular cross section. To achieve maximum flux density, the core should ideally be of circular cross-section, too. A 'stepped core', then, describes the way in which the widths of the outer laminations of a transformer's core are progressively reduced ('stepped') in order to achieve a roughly-circular cross-section.

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.
What is the name of coating on CRGO laminations?
The coating on CRGO (Cold Rolled Grain Oriented) laminations is typically referred to as an insulation or dielectric coating. This coating is usually made of organic materials, such as epoxy or varnish, and serves to reduce eddy current losses and prevent electrical shorting between the laminations. It helps enhance the magnetic properties and overall efficiency of the transformer or electrical device in which the CRGO laminations are used.
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 Laminations?
CRGO laminations, or Cold Rolled Grain Oriented laminations, are thin sheets of silicon steel used primarily in the manufacturing of electrical transformers and other magnetic applications. These laminations are processed to have a specific grain orientation, which enhances their magnetic properties and minimizes energy losses during operation. The cold rolling process ensures a smooth surface and precise thickness, making them ideal for high-efficiency electrical devices. Their use contributes to improved performance and reduced energy consumption in electrical systems.

Why rotor are connected to thin laminations?
Rotors are connected to thin laminations to reduce energy losses due to eddy currents. By using thin layers of magnetic material, the path for these currents is disrupted, minimizing heat generation and improving efficiency. This design also enhances the overall magnetic performance and reduces weight, making the rotor more effective in applications like electric motors and generators. Additionally, thin laminations provide better control over magnetic properties.

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.
