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.
Heat generally demagnetizes a magnet (if it's heated sufficiently and kept there for long enough, that is). Also, above a temperature known as the Curie temperature (which is different for different materials), ferromagnetic materials become paramagnetic (in everyday terms: magnetic things, like iron, stop being strongly attracted by magnets). A magnet which is demagnetized by raising it above its Curie point and then cooled down again will no longer be a magnet (assuming it hasn't been re-magnetized through application of an external magnetic field), though it WILL be attracted by other magnets. Cold doesn't have much of an effect.
Cold temperatures actually increase the magnetism of a magnet; actually, at a certain high temperature the material loses all magnetic properties that cannot be gained back by cooling.
Magnetic force has to do with how the atoms and electrons are arranged in a metal. Temperature does not affect this.
bust your move!!
magnets make the radishes grow larger. i noticed that the magnets also made the radishes produce more leaves.
Refrigerators use magnets on the door the keep the cold air in, Same with the freezer door.
There is some evidence that the electro magneto field from high tension power lines can affect honey bees but nobody seems to be absolutely certain.
My answer id they have different shapes and colors.
only one... but there are difrent shapes...
yes
Cold. If magnets get overheated, they can cease to work all-together.
yes i tried and different liquids affect the strength of magnets
Yes, they do, but their affect is minimal. Magnets with their magnet fields affect inductors profoundly, but don't do to much to capacitors.
cold temperature affects the magnets strength by making it stronger
no
yes temp does affect the strength of magnets. The cooler the magnet the stronger it gets.

No.
yes it can
Magnets do not affect plants in any way
They affect the magnetism so yes
