Show the magnetic field of bar magnet in a panoramic way.
A bar magnet having centre $O$ has a length of $4 $ $cm. $ Point $P_1$ is in the broad side-on and $P_2 $ is in the end side-on position with $OP_1 = OP_2 = 10$ metres. The ratio of magnetic intensities $H$ at $P_1$ and $P_2$ is
A bar magnet is placed north-south with its north pole due north. The points of zero magnetic field will be in which direction from the centre of the magnet
What is incorrect for current carrying solenoid
What is the magnitude of the equatorial and axial fields due to a bar magnet of length $5.0 \;cm$ at a distance of $50\; cm$ from its mid-point? The magnetic moment of the bar magnet is $0.40\; A m ^{2}$.
Two identical thin bar magnets each of length $l $ and pole strength $m$ are placed at right angle to each other with north pole of one touching south pole of the other. Magnetic moment of the system is
