Yes, magnets can stop working due to factors such as exposure to high temperatures, strong external magnetic fields, physical damage, and time. These factors can disrupt the alignment of the magnetic domains within the material, causing the magnet to lose its magnetic properties.
Magnets can stop working when their magnetic properties weaken or disappear. Factors that contribute to this loss include exposure to high temperatures, physical damage, and demagnetizing fields.
Working magnets generate magnetic fields through the alignment of their atomic particles, specifically electrons, which creates a magnetic force. This force is what allows magnets to attract or repel other objects.
Kinda-sorta, but not really. While magnets can lose some of their power over time, particularly if heated or hit, there's no solid proof that a magnetic bracelet ever has worked. So if the magnets didn't do anything to start with, losing the magnets wouldn't change anything.
Yes, magnets can lose their magnetism over time, especially if they are exposed to high temperatures or strong magnetic fields. This process is known as demagnetization.
No. Some metals are non-magnetic (technically, "diamagnetic," they're actually very weakly repelled by magnets). Gold, silver, and copper are all diamagnetic. Also, the alloys used in United States coins and certain types of stainless steel are either non-magnetic or only weakly attracted by magnets. Scientists working on or near very strong magnets often use special tools made of non-magnetic alloys to avoid mishaps.

The magnetic strip on your card may not be working due to wear and tear, damage, or demagnetization caused by exposure to magnets or electronic devices.

When you flip the switch to turn off the electromagnet, the flow of electric current stops, which in turn stops the magnetic field from being produced by the coil. The magnetic field is generated by the flow of electric current through the coil, so cutting off the current stops the magnetic field, causing the electromagnet to stop working.
You can make a pencil float in the air by using powerful magnets. Place a magnet above and below the pencil to create a magnetic field that counteracts gravity and lifts the pencil. Be cautious when working with magnets to avoid any accidents or damage.
electronic devices that get too close to magnets, can stop working properly.
A synchronous motor is a three phase motor, which uses a magnetic field created by permanent magnets or a DC electromagnet on the rotor (usually). The stator windings have 3 phase voltages applied, and coupled with the DC field, create a rotating magnetic field that drives the motor at synchronous speed.
Neodymium magnets can retain their magnetic strength for a very long time, often decades or longer. However, they can slowly lose their magnetism over time due to factors such as exposure to high temperatures or strong magnetic fields. The depolarization process can take years to happen noticeably.
One way to re-magnetize a horseshoe magnet is to stroke it along one direction with a strong magnet multiple times. This process can help realign the magnetic domains in the magnet and restore its magnetism. Alternatively, you can also subject the magnet to a strong magnetic field using specialized equipment.
