a butterfly is sitting on a wire of length 4.8 m. the combined mass of the butterfly and the wire is 546 g. a magnetic field of strength of 2.8 t is applied in the region perpendicular to the wire. a current flows through the wire as such that the force due to the magnetic field balances the weight of the butterfly and the wire. what is the magnitude of the current (in a)? round off to two decimal places



Answer :

Magnitude of current = 39mA

The gravitational force balances with the magnetic force experienced by the current carrying wire.

                            Mg= B×I×L

              (0.546) × (9.81)=(2.8)× I ×(4.8)
                        I = 0.39 A

Magnitude of current = I = 39mA
