ELECTRO-MAGNETIC INDUCTION

Important Terms Used In Magnetic Induction

A bar magnet of magnetic moment 0.4 Am^(2) is placed in a uniform magnetic field of induction 5 xx10^(-2) tesla. The angle between the magnetic induction and the magnetic moment is 30^(@) . The torque acting on the magnet is

The bar magnet produces magnetic induction of 4 xx 10^(-5)T at a point 10 cm from centre on the axis of magnet. The magnetic moment is The bar magnet produces magnetic induction

Which of the following is NOT the unit of magnetic induction?

A bar magnet is oscillating in a uniform magnetic field of induction 0.4xx10^(-5)T . When the frequency of the oscillating bar magnet is double due to increasing magnetic field, the increase in magnetic induction is
