Nickel shows ferromagnetic property at room temperature. If the temperature is increased beyond Curie temperature, then it will show

The work done in turning a magnet of magnetic moment M by an angle of 90^o from the  meridian, is n times the corresponding work done to turn it through an angle of 60^o. What is the value of n ?

Due to the earth’s magnetic field, charged cosmic ray particles

In which type of material the magnetic susceptibility does not depend on temperature?

The angle of dip is 90^o at 

A bar magnet is placed with its north pole pointing earth’s north. The points of zero magnetic field will be which direction from the center of the magnet?

A bar magnet having  a magnetic moment of 2 × 10 ⁴ JT ^-1 is free to rotate in a horizontal plane.  A horizontal magnetic field B = 6 × 10^-4 T exists in  the space. The work done in taking the magnet slowly from a direction parallel to the field to a direction 60^o from the field is

A bar magnet has a magnetic moment of 2.5 JT^-1 and is placed in a magnetic field of 0.2 parallel to anti parallel position relative to the field direction is

A diamagnetic substance is brought near a strong magnet, then it is
