Not until the magnet reaches its "Curie point" or temperature. Then magnetic activity ceases.
They are all induced by some external magnetic field. Once upon a time this was always the earth's magnetic field ... (which is a dynamo effect - a spinning conductor) but these days is usually from an elector-magnet.
i really dont know
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.
I did a science fair experiment on this last year. It is found that magnets that have higher temperature were weaker. to support this claim you should research about the "curie point" which basically says that this is a temperature ( really hot) where the magnet will lose its magnetic properties.
A Magnetic Force
Where is the magnetic field around a magnet strongest? Answer: A magnetic field is strongest around the poles. Your welcome! :)
it produces magnetic field that can attract ferromagnetic or paramagnetic substances that fall in its vicinity or in its field.

Design an experiment with a magnet and something that measures the magnetic field strength (say, a paper clip and a ruler -- the farther away from the magnet your paper clip gets pulled, the stronger the field). Then, measure the field strength with the magnet at different temperatures. Record all of your measurements. Remember: don't do anything different from measurement to measurement except for changing the magnet temperature.
If you have a magnet, you can see if the magnet is attracted to the material in question.A diamagnetic substance can be identified by weak repulsion in the presence of a magnetic field.A non magnetic substance has no effect in the presence of a magnetic field provided the field is weak.Because if the field is strong enough the tiny electronic magnets may get rearranged so as to have an effect.
The magnetic force of a magnet is strongest at its poles. This is because the field lines of the magnetic field are most concentrated at the poles where they enter and leave the magnet. At the poles the magnetic field is strongest and the force is the greatest. The north pole is where the magnetic field lines enter the magnet. The south pole is where the magnetic field lines leave the magnet. The magnetic field lines are most concentrated at the poles. The magnetic force is greatest at the poles.
It will not have any affect at all HaYLEy
