Two identical thin bar magnets each of length l and pole strength m are placed at right angles to each other with north-pole of one touching south-pole of the other, then the magnetic moment of the system is

Options

  1. Aml
  2. B2 ml
  3. C2 ml
  4. Dml / 2

Correct answer

C. 2 ml

Step-by-step solution

Here, distance between two poles = 2 1 Hence, M = m 2 l = 2 ml
