The small magnets each of magnetic moment $10 \,A-m^2$ are placed end-on position $0.1\,m$ apart from their centres. The force acting between them is....$N$
A long magnetic needle of length $2\,L$, magnetic moment $ M$ and pole strength $m$ units is broken into two pieces at the middle. The magnetic moment and pole strength of each piece will be
Two short magnets of magnetic moment $1000$ $A{m^2}$ are placed as shown at the corn ers of a square of side $10\, cm$. The net magnetic induction at $P$ is....$T$
Two identical short bar magnets are placed at $120^{\circ}$ as shown in the figure. The magnetic moment of each magnet is $M$. Then the magnetic field at the point $P$ on the angle bisector is given by
What does the analog (similarity) of bar magnet’s and solenoid’s magnetic field lines suggest ?
