Materials which can be magnetized are called magnetic materials. When magnetized, such materials create a magnetic field around them. Some of the significant features of magnetic materials are given below:
Some materials are magnetized even below without the application of any magnetic field and become more magnetic then a week magnetic field is applied to such materials. Some materials show a magnetic response in a direction opposite to that of any extremely applied field's. This may be surprise to some, but all matter is magnetic. It is just that some materials are much more magnetic then others. The main distinction is that in some materials there is no collective interaction of atomic magnetic moments, where as in other materials there is a very strong interaction between atomic moments.

Im having trouble understanding these,, could someone explain them in lamens terms
The process of apparent change in frequency (or wavelength) of the light because of relative motion among the source of light and the observer is known as Doppler's effect.
M is the magnetic moment of bar magnet and T is time period of oscillation. If we make M as M/4 then what will be the time period
i want to do experiment online
An object is thrown downward from a 150 cliff so that it makes an angle of 30 with the horizontal. (a) How fast will it be going when it hits the ground? (b) How long will it take
What do you understand by "Absorption coefficient"? which is a better absorber of sound, glass or fibre glass?
Q State Lenz's law. Lenz's law declares that the induced current produced in a circuit always flows in such a direction that it opposes the change or cause that produces it.
