A small flat search coil of area `5 cm^(2)` with 140 closely wound turns is placed between the poles of a powerful loud speaker magnet and then quickly snatched out of the field region. The total charge flown in the coil is 10.5 mC. If the resistance of the coil is `0.6 Omega`, what is the field strength of the magnet ?
