A sodium ion is made when a sodium atom loses an electron and becomes positively charged. A chloride ion forms in the opposite way when a chlorine atom gains an electron to become negatively charged. Just like two opposite magnet poles, positive and negative charges attract one another. So ...
Magnetic resonance imaging(MRI), using magnetism and radio waves, can be used to image (produce a likeness of) the blood vessels. Larger vessels, such as the carotid arteries in the neck, can be imaged using this technique. Future software and hardware improvements may allow screening of the ...
Tumorsthat originate from brain cells or those that metastasizefrom other organs can affect brain function in two ways. The tumor can destroy brain cells so that their function is lost, or the tumor can take up space and cause pressure and swelling that affects brain cell function. This may ...
Some electricity will produce magnetism, Some don't. Some magnetism will produce electricity, But some magnetism does not produce electricity. Electricity is not always electricity, It's not all magnetic. Magnetism is not necessarily all magnetism, It's not always electricity. Electricity is super-...
The way I see it is if a black hole did any of that, it would quickly cease to exist as it lost so much mass. The point source of mass inside a black hole is probably nonsense as such would not spin, and black holes spin (we see from their event horizons). We know that ...
