a) Briefly discuss about the properties of magnets?
Answers
Explanation:
They are: Attractive Property – Magnet attracts ferromagnetic materials like iron, cobalt, and nickel. Repulsive Properties – Like magnetic poles repel each other and unlike magnetic poles attract each other. Directive Property – A freely suspended magnet always points in a north-south direction.
Answer:
what is a magnet
a magnet is defined as
an object which is capable of producing magnetic field and attracting unlike poles and repelling like poles.
properties of Magnet
following are the basic properties of magnet:
when a magnet is dipped in iron filings, we can observe that the iron filings cling to the end of the magnet as the attraction is maximum at the ends of the magnet. These ends are known as poles of the magnets.
magnetic poles always exist in pairs.
whenever a magnet is suspended freely in mid-air, it always points towards north-south direction. Pole pointing towards geographic north is known as the North Pole and the pole pointing towards geographic south is known as the South Pole.
like poles repel while unlike poles attract.
the magnetic force between the two magnets is greater when the distance between these magnets are lesser.
