If the horizontal component of earth's magnetic field at a place is $2.8 \times 10^{-5}$ T and the magnetic field of the earth at this place is $5.6 \times 10^{-5}$ T, then the inclination at the place is:
The magnetic susceptibility is negative for:
A vibration magnetometer is used at two different places \(A\) and \(B\) on the earth. The time period of a magnet suspended freely in the magnetometer at \(A\) is twice that at \(B\). If the horizontal component of the earth's magnetic field at \(B\) is \(32\times 10^{-6}\ \text{T}\), then its value at \(A\) is
A short bar magnet placed with its axis at \(45^\circ\) with a uniform external magnetic field of \(28.3\times 10^{-3}\,T\) experiences a torque of magnitude equal to \(3.6\times 10^{-5}\,J\). The magnitude of magnetic moment of the magnet is nearly
Two short magnets of equal dipole moments \(M\) are fastened perpendicularly at their centers. The magnitude of the magnetic field at a distance \(d\) from the centre on the bisector of the right angle is \((\mu_0=\text{Permeability of free space})\)
A magnetic needle free to rotate in a vertical plane parallel to the magnetic meridian has its north tip pointing down at \(30^\circ\) with the horizontal. The horizontal component of the earth's magnetic field at the place is \(0.3\;G\). Then the magnitude of the earth's magnetic field at the location is
A steel wire of length \(l\) and magnetic moment \(M\) is bent into a semicircular arc of radius \(R\). The new magnetic moment is
Consider the following statements:
Statement A: Magnetic monopoles do not exist and therefore magnetic field lines form closed loops.
Statement B: A bar magnet makes an angle of \(30^\circ\) with a uniform magnetic field. If the maximum torque experienced by the magnet is \(3.464 \times 10^{-5}\,\text{Nm}\), the potential energy of the system is \(3 \times 10^{-5}\,\text{J}\).
Statement C: A superconductor is a perfect ferromagnetic material.
On the magnetic meridian at some place of the Earth’s surface the vertical component of Earth’s magnetic field is \(0.433\,G\) and the dip angle is \(60^\circ\). Then the magnetic field of the Earth at this place is:
