Permanent magnets
magnetic
A permanent magnet (in contrast to an electromagnet).
That property is called "inertia".
It is called inertia.
Tapes depend on their magnetic properties to hold the data loaded, so storing a magnet next to them could well upset the information on the tapes
why should you keep diskettes away from magnetic sources
The force that allows objects to keep on doing what they are already doing is called inertia. Inertia is the tendency of an object to resist changes in its state of motion.
No, the magnetism of the Earth does not keep us on the Earth in the same way that gravity does. Gravity is the force that attracts objects toward the center of the Earth, keeping us grounded. Earth's magnetic field, on the other hand, helps protect the planet from solar radiation and guides compass needles.
The bar is called a keeper or a magnetic keeper. It helps to preserve and maintain the strength of the magnet by completing the magnetic circuit and preventing the loss of magnetism.
Magnetic separation is commonly used in everyday objects like credit cards (to store information), refrigerators (to keep doors closed), and speakers (to convert electrical signals into sound). It is also used in recycling processes to separate magnetic materials from non-magnetic ones, such as in sorting waste or extracting metals from ores.
Inertia is the quality that makes objects tend to keep moving. Inertia is the tendency of an object to resist changes in its motion, whether that motion is at rest or in motion.
Some staplers have small magnetic strips to help keep staples in place, but in general, staplers are not inherently magnetic.
