Sample questions

1. 1.For the same short magnet (m = 0.48 J/T) at 10 cm, the field on the equatorial (normal-bisector) line is:
   • A.0.96 G along the axis direction
   • B.0.48 G, directed opposite to the magnetic moment
   • C.0.48 G, along the magnetic moment
   • D.zero
2. 2.![fig52_field_lines.png]() Panel (a) of the figure shows the field of a bar magnet and panel (b) shows the field of a current-carrying finite solenoid. At large distances the two external patterns look very similar. What does this similarity, shown in the figure, best demonstrate?
   • A.A current-carrying solenoid behaves like a bar magnet, i.e. as a magnetic dipole
   • B.A bar magnet carries a real electric current along its axis
   • C.A solenoid produces an electric field identical to that of a dipole
   • D.The magnetic field of a solenoid forms open lines unlike that of a bar magnet
3. 3.A closely wound solenoid of 2000 turns and area 1.6 x 10^-4 m^2 carries 4.0 A. Its associated magnetic moment is:
   • A.0.64 A m^2
   • B.1.28 A m^2
   • C.2.56 A m^2
   • D.0.32 A m^2
4. 4.For a short bar magnet, the ratio of the axial field to the equatorial field at the same distance r is:
   • A.1 : 1
   • B.1 : 2
   • C.2 : 1
   • D.4 : 1
5. 5.A paramagnetic material is placed in a magnetic intensity H = 5 x 10^3 A/m and acquires a magnetisation M = 2.5 x 10^-2 A/m. Its magnetic susceptibility is:
   • A.5 x 10^-6
   • B.2 x 10^5
   • C.5 x 10^-2
   • D.1.25 x 10^2
