What is incorrect for current carrying solenoid
its pattern of field lines just like pattern of field lines of bar magnet
it is used to produce uniform field
its magnetic field does not depends on radius of cross section of frame
when it is freely suspended it always stays perpendicular to magnetic meridian
The magnetic field due to a short magnet at a point on its axis at distance $X \,cm $ from the middle point of the magnet is $200 $ $Gauss$. The magnetic field at a point on the neutral axis at a distance $ X \,cm$ from the middle of the magnet is.....$Gauss$
A magnetic needle is kept in a non-uniform magnetic field. It experiences
Define the intensity of magnetic field.
Of the following Fig., the lines of magnetic induction due to a magnet $SN$, are given by
A small bar magnet has a magnetic moment $1.2 \,A-m^2$. The magnetic field at a distance $ 0.1\, m $ on its axis will be : ($\mu_0 = 4\pi \times 10^{-7} \,T-m/A$)
