A 25 cm diameter coil consists of 21 turns of cylindrical, Ask an Expert

Academics

A 25 cm diameter coil consists of 21 turns of cylindrical copper wire 2.2 mm in diameter. A uniform magnetic field, perpendicular to the plane of the coil, changes at a rate of 9 x 10^-3T/s. Determine the current in the loop in milli-amps ( the resistivity for copper is 1.72x 10^-8Ohm.meter).
