Magnetic field lines are denser at the middle of the magnet.
Data:R=10 OHM N=1000 MAGNETIC FIELD=5×10^-4 tesla T=0.1SECOND A=1M^2 INDUCED EMF=?
Induced EMF = (Number of turns x Magnetic field x Area)/change in Time.
N * A * B / (T)
1000 * 1* 5×10^-4 / ( 0.1 ) = 5
Induced emf is equal to 5 volt

The magnetic moment m=6.7×10⁻²
The moment of inertia I=7.5×10⁻⁶
The time is 10 sec
The magnitude of the magnetic field.
The time period for the 10 oscillation is
Now the relation of the magnetic field with the time period and magnetic moment of inertia.
Putting the above values
So the magnitude of the magnetic field is 0.01 T
near at the poles magnetic field lines are denser
hope it will help you ✌️✌️
Study of the displacement of floating diamagnetic bodies by a magnetic field. The authors analyzed the motion of diamagnetic bodies that float on diamagnetic liquids. The motion was inspired by the deformation of the diamagnetic liquid surface by a magnetic field, called the 'Moses effect'.
The magnetic lines of a magnet are denser near the poles of the magnet.
As given in diagram below shows the magnetic field ejected from a common pencil magnet with magnetic lines coming out of the magnet in an elliptical pathway from North Pole (N) to South Pole (S), as we can see that the pathway is denser at the poles of the magnet denoted by (N) and (S) rather than at the sides. Therefore, the magnetic lines of a magnet are denser in the poles of the magnet.
that is certainly possible, because the fully magnetized state is most likely not the ground state, but the system can lower its energy when breaking into a multi-domain state. the time scale on that happens depends on temperature and the energy barriers that separate the local minima in the free energy from each other. as an example, if you a ferromagnet with a hammer, it can demagnetize as well by finding a lower energy state.
