A butterfly is sitting on a wire of length 4.3 m. The combined mass of the butterfly and the wire is 554 g. A magnetic field of strength of 3.5 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 [Hint: equate the magnetic force on the wire and the total weight of the butterfly and the wire]
A charged particle of charge 5.2 mC (milli-Coulomb) is moving with a speed of 10 m/s in a region of a magnetic field of 5.5 T, which acts at an angle of 30 degrees to its motion. What is the magnitude of the magnetic force on the charge due to the field? Enter your number up to TWO decimal place.
