Question

41.
What are (a) magnetic materials, and (b) non-magnetic materials ? Name two magnetic materials and two
non-magnetic materials.
42. What is meant by the poles of a magnet ? Where are the poles of a bar magnet located ? Draw a sketch to
show the poles of a bar magnet.​

Answer 1

Answer:

MARK ME AS BRAINLIST PLEASE

Explanation:

The materials which get attracted towards a magnet are magnetic – for example, iron, nickel or cobalt. The materials which are not attracted towards a magnet are non-magnetic materials. Examples of non-magnetic materials include rubber, coins, feather

Poles of magnet refers to the direction of magnet. They are located at the sides of the magnet

Answer 2

Answer:

MAGNETIC MATERIAL= Magnetic materials are materials studied and used mainly for their magnetic properties. The magnetic response of a materials is largely determined by the magnetic dipole moment associated with the intrinsic angular momentum, or spin, of its electrons.

NON-MAGNETIC MATERIAL= The materials which are not attracted towards a magnet are non-magnetic materials. Examples of non-magnetic materials include rubber, feather and leather.

two magnetic materials are metal and iron

two non-magnetic materials are rubber and leather

A magnet is any object that produces its own magnetic field that interacts with other magnetic fields. Magnets have two poles, a north pole and a south pole. The magnetic field is represented by field lines that start at a magnet's north pole and end at the south pole.
