Magnetism

Magnetic length of a bar magnet is

A magnet of magnetic moment 10 Am^(2) has magnetic length 5 cm.The strength of magnet is

The dimensional formula for Magnetic Moment of a magnet is

A short bar magnet has a magnetic moment of 0.39 J "T"^(-1) . The magnitude and direction of the magnetic field produced by the magnet at a distance of 20 cm from the centre of the magnet on the equatorial line of the magnet is

If a magnet is hanged with its magnetic axis then it stops in

Magnetic induction and magnetic flux differ in the dimensions of

A curve between magnetic moment and temperature of magnet is

Magnetic moment for a solenoid and corresponding bar magnet is

The perio of oscillation of a magnet in vibration magnetometer is 2 sec. The period of oscillation of a magnet whosr magnetic moment is four times that of the first magnet is

Assertion: Magnetic field strength at a point on axial line of a bar magnet is along South to North pole of magnet. Reason: The magnetic field strength can never be along North to South pole of magnet.
