What is Core: Definition and 484 Discussions

Intel Core are streamlined midrange consumer, workstation and enthusiast computers central processing units (CPU) marketed by Intel Corporation. These processors displaced the existing mid- to high-end Pentium processors at the time of their introduction, moving the Pentium to the entry level. Identical or more capable versions of Core processors are also sold as Xeon processors for the server and workstation markets.
As of June 2017, the lineup of Core processors includes the Intel Core i3, Intel Core i5, Intel Core i7, and Intel Core i9, along with the X-series of Intel Core CPUs.

    Core Material for Long-Run Solenoid Circuits

    http://img16.imagevenue.com/img.php?loc=loc76&image=054_doorbell1.jpg I am building a circuit such as the one above. The only difference is that it will be running for long periods of time. So heat becomes an issue. To make the most efficient and strongest electromagnet I am wondering...

    How to build a transformer and find core

    In my car the OEM amplifier runs dual-voice coil subs. Its a SMT PCB with all ICs on even the outputs, no SMPS so its just 12V for the rails and the outputs are already bridged. Easy to see why many junk it and use an aftermarket amplifier come upgrade time. But I want to try to use it as is...

    Mining Metals from the Core: Impact on Earth's Magnetic Field & Climate

    If someday we discover how to mine metals from the core, will it have any effect on the magnetic field or the climate of the Earth due to reduction of heat in the core as the metal mined will be hot and will slowly drain the heat of the core.

    Atomic radius - core charge vs energy level

    which one is more important in determining the size of an atom? for example - Berilium has a smaller radius than Lithium because it has a greater core charge, but what about Nitrogen vs Berilium? Nitrogen has a greater core charge, but it has electrons in the 2p subshell whereas Berilium only...

    Earths magnetisim is based on the rotation of the earths core

    I watched the movie "The Core", in that movie they say that the Earth's magnetisim is based on the rotation of the Earth's core(molten metal spinning at high speeds) so does it have to be liquid metal or anything hot rotating at high speeds could creat a magnetic field? is it possible to create...

    Could the Earth's Core be a Fission Reactor?

    Could the center of the Earth's core be a critical mass of U-235 or other heavy metals, sustaining a fission reaction. (or might fusion be possible with the presures and magentic fields there? ). If not Earth what about Jupiter or larger exra solar planet? Merlin

    What if the Earth's Core Stopped Spinning?

    After watching, "The Core"(2003), a few questions popped into my mind at the painful display of physics: If the core really did stop spinning (hahahaha, like that would happen), what would be the result? Would it affect gravity at all? (I realize how asinine I sound, but I really need to...

    What is the mechanism behind the heating of the Earth's core?

    Heating of the Earth's core must have a logical solution, which led me to this idea, the work done by gravity on vibrating molecules throughout the Earth moves the surface heat of the earth towards the Earth's core,amplifing it as it moves to the Earth's center.This is backed up by the...
