Your monitor may have a degauss function built into it.
It's usually accessed through an on screen configuration menu you can bring up by pressing a button or dial on the front of the monitor.
You may have to search around a bit. The symbol for the degauss function is usually a big U (like a horseshoe magnet), with a slash through it.
It's also possible to correct by using another magnet and moving it in a certain kind of pattern around the monitor.
Basically you hold your magnet close to the screen, in the center.
Then move it, in a spiral motion, progressively outwards (towards the edges of the screen), and at the same time progressively further away from the screen.
Watch the screen while you do this to see how it's going.

Your screen has been magnetised, so it needs to be demagnetised or degaussed.
There is a degauss circuit in all CRTs that is energized when the monitor is switched on.
Two caveats:
1) After degaussing, the degauss circuit needs about 20 minutes to cool off before it is effective again.
2) The degauss circuit is designed to solve minor magnetic problems from the Earth's magnetic field, not annoying little boys with more powerful magnets.
You could try using the degauss circuit several times, waiting 20 minutes between each time and it may improve it.
Or you could take the monitor to a computer or TV repair shop where they will have a much more powerful degauss wand or ring that will be capable of undoing the work of annoying little boys with magnets.

You should have a Degauss option in the monitors OSD menu. Try hitting that a few times. However, you will need to wait about 20 minutes between cycles for the degauss circuit to reset properly. If that is not having an effect then take the monitor to a TV repair shop and they will be able to use a much more powerful degauss wand or ring on it. It will take about 30 seconds to fix. I would strongly advise against strapping magnets to a drill. That looks like a good way to get a magnet embedded in the wall, or even worse in you.

You have two choices. 1) Deal with it or 2) Get yourself a new monitor. Unfortunately the magnet pulled you screen colors all together which causes the screen to be messed up. Certain colors are always in the front so you'll always have the rainbow effect.
Sorry, I wish there was a better answer.

What you need is a degaussing tool. They run from $40 - $80.
You might just want to go out and buy a nice new LCD monitor. You'll usually never be able to get it back to as good as before.

You need to buy a new monitor. It can be fixed, but for a larger cost than to just buy a new one. It would be a good idea to keep magnets far away from computers. So I would suggest not allowing any magnets in the room where you have your computer just to be safe.

If it won't go away in a few days, even a week, then you're in trouble. But a big stick (with nails embedded), around the back of your nephews legs, will ensure you trouble free monitoring for the foreseeable future.

I would suggest you degause it. you can buy a degauser. It is, essentially, a lamp cord rolled up and taped together. you plug this is and the electricity goint through the lamp cord sets up an electromagnetic field and this, hopefully, will bring your monitor back to normal.--I'm assuming this is a CRT monitor-not a flat screen.

if it does not go away in a couple of days its there forever, nothing you can do! a friend set a clock radio on his not thinking about the magnet on the speaker. new monitor!

I am sorry to say this but the Monitor has suffered significant damage and you would need to get it repaired..You cannot do anything on your own to rectify the problem...
Take it to a computer hardware technician...
