Can two magnetic lines of force intersect?
Justify your answer.
The susceptibility of a magnetic material is -0.085.
Identify the magnetic type of the substance.
A specimen of this material is kept in a uniform magnetic field. Draw the modified field pattern.
Two bar magnets having same geometry with magnetic moments M and 2M are firstly placed in such a way that their similar poles are on the same side and its period of oscillation is T1. Now the polarity of one of the magnets is reversed and its time period becomes T2. Then,
How can paramagnetic and diamagnetic material rods be distinguished in a magnetic field?
The magnetic moment has dimensions of
Two magnetic materials A and B have relative magnetic permeabilities of 0.96 and 500. Identify the magnetic materials A and B.
Distinguish the magnetic properties of a dia-, para- and ferromagnetic substances in terms of:
i. susceptibility
ii. magnetic permeability
iii. coercivity
Give one example of each of these materials.
Draw the field lines due to an external magnetic field near a diamagnetic substance.
Draw the field lines due to an external magnetic field near a paramagnetic substance.
Why does a paramagnetic substance display greater magnetization (for the same magnetizing field) when cooled?
A small bar, when placed near a magnet is repelled by it. This is because the bar is made of:
An electron in an atom revolves around the nucleus in an orbit of radius 0.5 . The frequency of revolution of the electron is 1010 MHz.
Calculate the equivalent magnetic moment.
