temperature does not affect the magnet.

Does the Temperature of a magnet affect its strength

NO!!! the strength of magnet is not affected by temperature

every magnet has a curie temperature, the curie temperature is the temperature the magnet has to reach to lose its strength. every magnet has a different curie temperature, the stronger the magnet is in room temperature the lower the curie temperature is.

although temperature does not affect a magnet to extremely, there is a small difference nonetheless. the colder the magnet the stronger the pull, and the hotter the magnet the weaker the pull.

As the temperature increases the strength decreases, and vice versa

Yes, it does due to the magnetic force coming from the magnet. After a period of time the magnet that is in lower temperature increases while higher temperatures decrease.

yes it does affect magnets ! though cold has little effect on the properties of a magnet , but heat drastically brings about change in properties of a magnet. With increasing temperature, the magnet will gradually lose magnetization until a certain temperature (called the Curie temperature) where the magnetization goes away entirely. In addition to this effect, the domains of the magnet will have a greater chance of changing orientation, further weakening the overall magnetic effect.

A permanent magnet can affect magnets and electromagnets.

Yes it does if you freeze the magnet the magnetic field gets larger and if you heat it up the magnetic field gets smaller

yes because the magnet will reach its curie temprature and loose stregth

If you drop a magnet, you can potentially make it lose some of its magnetism. Striking it with a hammer, exposing it to electric charges, and extreme temperature changes (rapid temperature change from freezing to boiling for example) can affect its magnetism.

Yes, It doesPierre Curie (Marie's husband) discovered that at an elevated temperature, a magnet loses its magnetic properties, now known as the Curie Point.

Not until the magnet reaches its "Curie point" or temperature. Then magnetic activity ceases.

If a magnet is heated to a high temperature it will lose its magnetism.

Heat, because it affects magnetic molecules, causes a drop in magnetic field strength. Cooling a magnet has the opposite effect: reducing the resistance in the molecules and increasing the net field strength.

A permanent magnet (i.e. not an electromagnet) will be demagnetised by heating it.

yes but it depends on the type of magnet and how strong it is

A magnet will not affect the Mirena IUD.

Yes, rust will cause a magnet to be less effective.

It is the temperature at heating above it , a magnet goes from ferromagnetic state to paramagnetic state. It is also used for ferroelectric to paraelectric transition.

higher the temperature, lower is the magnetic strength..

Heat and cold both make magnets stronger, but cold temperatures make magnets stronger than heat does. Actually, oly cold temperature make magnets stronger, you can actually try, hold one little magnet on your hand for like 30 seconds or something and you can realize that your magnet is really less stronger Unfortunately this guy is wrong ^^^^^^ Cold makes a magnet stronger and heat can actually take its magnetic domains away. When a magnet is supercooled it becomes stronger because the atoms are moving slower and are thicker which make a stronger positive or negative side of a magnet. Heat can ruin a magnet. There is a very hot temperature for every magnet called a Curie Temperature, which is when a magnet is no longer magnetized. For instance, and iron magnets Curie Temperature is about 1,000°C! This happens because the random motion of atoms increases in speed which disturbs the magnets magnetic domains. (well... he's somewhat right) =) ----------------------------------------------------------------------------------------------------- You both are right.
