Yes, a magnet can potentially ruin a bus pass if it contains a magnetic strip. The strong magnetic field may disrupt or erase the data stored on the strip, rendering the pass unusable. However, if the bus pass is made of a different material, such as a smart card with an embedded chip, it may not be affected. It's best to keep magnets away from any card with a magnetic strip.

Can magnet pass through wood?

yes it can


If you circulated copper wire to magnet and pass current through copper wire it then power of magnet is incrase?

When you pass an electric current through a copper wire that is wound around a magnet, it creates a magnetic field that aligns with the magnetic field of the magnet. This process strengthens the overall magnetic field around the magnet, effectively increasing its power. This principle is the basis of how electromagnets work.


How long is a bus pass good for?

The duration of a bus pass can vary depending on the transportation agency or city issuing it. Typically, bus passes can be valid for a day, a week, a month, or even longer periods. It's essential to check the specific details when purchasing a bus pass to understand its validity period.


Can a magnet pass through water?

The magnet should be able to extract iron out of water as water and iron are not chemically combined. If the water and iron would have chemically combined then it would be futile to separate them using a magnet. Note that the stronger the magnet the more iron will be removed from water.


Is an magnet an example of selective permeability?

No, a magnet is not an example of selective permeability. Selective permeability refers to the ability of a membrane to allow certain substances to pass through while blocking others, typically in biological contexts. A magnet, on the other hand, exerts a force on certain materials (like iron) based on their magnetic properties, rather than selectively allowing substances to pass through.
