Answer: (D) 1 × 10⁻³ N. The force of attraction between the unlike magnetic poles is 1×10⁻³ N. This is calculated using the formula involving permeability of free space, magnetic pole strengths and distance.
The correct answer is: (C) M. When a bar magnet is cut into two equal parts perpendicular to its axis, each piece retains the same magnetic moment M/2. Placing one over the other with opposite poles touching (B over A) ...
The correct answer is: (D) Highly negative. A superconductor exhibits perfect diamagnetism, meaning it completely expels magnetic fields from its interior (Meissner effect). This results in a magnetic susceptibility of −1, which is highly negative, indicating a strong opposition to ...
The correct answer is: (D) Stationary charge. A stationary magnet does not interact with a stationary electric charge because magnetic fields affect only moving charges or magnetic materials. There is no magnetic force acting on a charge at rest, so ...
