no not really
Yes, a rusty magnet can still work, as rust primarily affects the surface and does not significantly alter the magnet's magnetic properties. However, the rust can interfere with the magnet's ability to adhere to ferromagnetic materials and may reduce its overall effectiveness. If the rust is extensive, it could eventually weaken the magnet's strength. Regular maintenance and cleaning can help preserve the magnet's performance.
the magnet gets weaker
Not measurably.
When you drop or heat a magnet, the domains may temporarily lose alignment, but once the magnet stops moving or cools down, the domains will realign and the magnet's strength will return. Dropping or heating a magnet will not permanently weaken it.
Rust can weaken magnets by creating a barrier between the magnet and the object it attracts, reducing the magnetic strength. The presence of rust can also interfere with the magnet's ability to create a magnetic field, diminishing its effectiveness. Regular maintenance and protection from moisture can help prevent rust and preserve the magnet's magnetic properties.
Water can temporarily weaken a magnet by disrupting the magnetic force between its molecules. However, once the water is removed and the magnet is dried thoroughly, its magnetic strength should return to normal. Prolonged exposure to water can cause rusting and permanent damage to the magnet.
A magnet Will pick up rust flakes And a magnet can get rusty looking however I don't think you can get much magnetism out of a piece of rust.
Rusty magnets can still attract and repel other magnets like regular magnets. The presence of rust on the surface does not significantly affect the magnetic properties of the magnet itself. However, excessive rust or corrosion may weaken the overall strength of the magnet.
I don't know how the rust spots got there but they wont effect the strength of the tiles
The Rust affects the magnet. The magnetic energy won't work as well cause it has to work thru the rust. So no, rusty magnets are not as strong as a nonrusty magnet
To weaken a magnet, you can heat it to a high temperature, subject it to mechanical shock, or expose it to a strong magnetic field in the opposite direction. These methods can disrupt the alignment of the magnetic domains within the material, reducing its overall magnetism.
When a magnet gets wet, the liquid acts as an electrical conductor when moving through the magnetic field and produces a voltage. You can test this theory by dropping a magnet in a fish bowl and watching the fish float to the top. Don't worry, it is only a mild electric shock and the fish should start swimming around again within a minute or so.
