Magnetic and electrical fields are related, and magnetism, along with gravity and strong and weak atomic forces, is one of the four fundamental forces in the universe. But none of those facts answers the most basic question: What exactly makes a magnet stick to certain metals? Or why don't...

Inside permanent magnets, the magnetism is produced by the electrons inside the material. Electrons have an intrinsic magnetic field around them. In permanent magnets, the magnetic fields of the electrons add together to produce a net magnetic field surrounding the magnet. In non-magnetic materials,...
ICSE-ELECTRICITY AND MAGNETISM -EXERCISE (SECTION I) (Long Answer Questions) How will you test whether a given rod is a magnet or not? 01:50 What is electromagnetism and how do you make an electromagnet? 01:47 Explain how electrons flow in a conductor? 02:00 Draw a circuit diagram for...
What unit is used to measure electricity? How does electricity cause magnetism? How is electricity produced from magnetism? How does induction work in physics? Is an ultrasonic sensor analog or digital? How did Michael Faraday contribute to electricity?
Stones, in this lesson, are not those hard and rough things found outside. Stone is an Imperial unit of measurement. Specifically, a stone is used to measure weight just like a pound is used to measure weight. A pound is a unit found in the Imperial and United States customary systems ...

When the current is turned off, the atoms return to their natural state (meaning in random directions), and the rod loses its magnetism. (Technically, it retains some magnetic properties but not much and not for very long). With a run-of-the-mill permanent magnet, like the ones holding ...
What is an electron spin in quantum physics? Who discovered electromagnetic radiation? Who discovered neutrinos? Who discovered nuclear magnetic resonance? Who published the first atomic theory? Who discovered that atoms have a nucleus? What is quantum physics used for?
