How can you make a magnet stronger without another magnet?
Place your weak magnet within the magnetic field of a much stronger magnet. Setting it right next to the magnet will produce the best result. The stronger magnet will actually help realign electrons that have spun out of axis since it’s creation. Stroke the weak magnet with your larger, stronger magnet.
How do you temporarily demagnetize a permanent magnet?
You should take an electromagnet that operates on some frequency (tens of Hertz) and creates enough large magnetic field to magnetise your permanent magnet. Then you switch on your electromagnet in the vicinity of the permanent magnet and go slowly back from the permanent magnet at the distance of several meters.
Where on the bar magnet do the iron filings are attracted most?
Like poles repel each other and unlike poles repel attract each other. Maximum iron fillings will stick to the ends of the bar magnet because at the ends of the magnet poles are located. The strength of the poles is maximum at the ends of the magnet.
Which direction does this point to when a loose hanging magnet is fixed?
SOLUTION: A freely suspended bar magnet always comes to rest in the North-South direction. The geographical North facing end of the magnet is its north pole and the geographical south facing end is its South pole….Fun with Magnets – NCERT – NCERT Questions.

In which direction does the magnet stop every time?
The end of the magnet that points towards North is called its North seeking end or the North pole of the magnet. The other end that points towards the South is called South seeking end or the South pole of the magnet. All magnets have two poles whatever their shape may be.
Can magnets remove salt from water?
Most recent answer. It does not. It prevents deposit of salts. So the treated water will leach the upper soil profile and will deposit all salts in the deep soils.
Does water ruin a magnet?
Water does not significantly affect a magnet’s strength except that small parts of some magnets may have a chemical reaction with water, so that some magnets have to be coated if they will be immersed in water for an extended period of time.
