What else can I help you with?
How long do germs live on inanimate objects?
up to six hours.
Magnetic poles always come in?
Pairs - although monopoles have long been speculated about!
Storing information in long-term memory?
A magnetic read write-head moves a cross a spinning disk changing the polarity of tiny magnetic particles in the disk(s). This can then be read at a later date.
Does a glass cup keep drink warm long?
No, a galss cup does not keep any drink warm long.
Instrument that makes small distant objects visible?
An instrument that makes small, distant objects visible is a telescope. Binoculars and scopes are also used for seeing long distance.
What are objects that keep their magnetic properties for a long time called?
Permanent magnets
Ojects that keep their magnetic properties for a long time are called?
magnetic
How long does a neodymium magnet typically last before losing its magnetic properties?
Neodymium magnets typically last for several decades before losing their magnetic properties.
What magnets are made from materials which retain their magnetic properties for a long time?
Permanent magnets.
Why is gravity stronger at long distances than electric or magnetic force?
Gravity is always attractive and acts on all mass, whereas electric and magnetic forces can be attractive or repulsive and only act on objects with electric charge or magnetic properties. Additionally, electric and magnetic forces diminish with distance faster due to the inverse square law, while gravity follows a simple inverse relationship with distance. This results in gravity being dominant at long distances.
What kind magnets are made from materials which retain their magnetic properties for a long time?
Permanent magnets are made from materials that retain their magnetic properties for a long time without the need for an external magnetic field. Examples include neodymium magnets and samarium-cobalt magnets. These materials have high coercivity, which allows them to maintain their magnetism over long periods.
How long does a magnet last before losing its magnetic properties?
The length of time a magnet retains its magnetic properties varies depending on factors such as the type of magnet and how it is used. Generally, permanent magnets can last for many years or even decades without losing their magnetism, while temporary magnets may lose their magnetic properties more quickly.
Why does a compass always work?
A compass works by aligning itself with the Earth's magnetic field. The needle of the compass is magnetized, pointing towards the magnetic north pole. As long as the Earth's magnetic field remains stable and the compass is not influenced by nearby magnetic objects, it will always point north.
What distinguishes a permanent magnet from a temporary magnet?
Permanent magnets do not lose their magnetic ability. Temporary magnets, however, gain magnetic properties when they are touched or moved by a permanent magnet. The properties of a temporary magnet dissipates over time after the permanent magnet is removed.
How long will magnetic water stay magnetized when take off the magnet?
What you have here is a classic example of "begging the question". Your question carries with it the implied (but erroneous) statement that water can be magnetized. Neither the hydrogen nor the oxygen which combine to produce the water molecule can be magnetized but, in an intense magnetic field at close to its melting point, oxygen will demonstrate some paramagnetic properties. Magnetized water is a myth but it is used quite frequently to remove money from peoples' wallets.
Why is austenite magnetic?
Austenite is not magnetic. It's an allotrope of iron, and has some alloying agents, but it only exists at high temperatures that are well above the Curie point of whatever iron alloy is heated. We know that metals that are magnetic will lose their magnetic properties above a certain temperature (called the Curie point), which varies for different metals and alloys. It is not possible for iron alloys (or any steels) to make the transition to austenite until well past the Curie point of the metal. Any magnetic properties the metal had will have long ago disappeared.
How long will a magnet last before losing its magnetic properties?
The lifespan of a magnet varies depending on factors such as the material it is made of and how it is used. Generally, permanent magnets can retain their magnetic properties for many years, even decades, if they are not exposed to extreme conditions or physical damage. However, over time, all magnets will gradually lose some of their magnetism due to factors like temperature changes and external magnetic fields.
