  - question: "A point pole has a strength of 4\u03C0 * 10^-4 weber. The force in newtons\
      \ on a point pole of 4\u03C0 * 1.5 * 10^-4 weber placed at a distance of 10\
      \ cm from it will be\n(A) 15 N. (B) 20 N. (C) 7.5 N. (D) 3.75 N."
    target: "Let's think step by step. The force between two point poles is given\
      \ by m_1m_2/(mu_0 4 \\pi r^2), in analogy to Coulomb\u2019s law. Plugging in\
      \ the values given in the question, we calculate that the force is approximately\
      \ 15 N. The answer is (A)."
  - question: 'The coil of a moving coil meter has 100 turns, is 40 mm long and 30 mm
      wide. The control torque is 240*10-6 N-m on full scale. If magnetic flux density
      is 1Wb/m2 range of meter is

      (A) 1 mA. (B) 2 mA. (C) 3 mA. (D) 4 mA.'
    target: Let's think step by step. The torque on a coil in a uniform magnetic field
      is given by BANI, where B is the magnetic flux density, A is the area of the
      coil, N is the number of turns, and I is the current. So we have that I = (Torque)/(BAN),
      or 240e-6/(1200e-6 * 100 * 1) = 2e-3. The answer is (B).
  - question: 'In an SR latch built from NOR gates, which condition is not allowed

      (A) S=0, R=0 (B) S=0, R=1 (C) S=1, R=0 (D) S=1, R=1'
    target: Let's think step by step. An SR latch is a set-reset latch; in the case
      where S=1 and R=1, the circuit has no stable state; instead a race condition
      will be produced within the circuit, so the device will be in an undefined state.
      So S=1, R=1 is an illegal question. The answer is (D).
  - question: 'Two long parallel conductors carry 100 A. If the conductors are separated
      by 20 mm, the force per meter of length of each conductor will be

      (A) 100 N. (B) 0.1 N. (C) 1 N. (D) 0.01 N.'
    target: Let's think step by step. The magnetic force-per-length between two current-carrying
      conductors is given by \mu_0 I_1 I_2 / (2 \pi r), where $r$ is the separation
      distance and I_1 and I_2 are the currents. Plugging in 100 A for I_1 and I_2,
      and 20 mm for r, gives 0.1 N. The answer is (B).
  - question: "In a 2 pole lap winding dc machine , the resistance of one conductor is\
      \ 2\u03A9 and total number of conductors is 100. Find the total resistance\n\
      (A) 200\u03A9 (B) 100\u03A9 (C) 50\u03A9 (D) 10\u03A9"
    target: 'Let''s think step by step. In lap winding, effectively two resistors
      are connected in parallel, so the actual resistance of each pair is 1 Ohm. Since
      we have 50 pairs, we get a total resistance of 50 Ohms. The answer is (C).'
