A power line carries a DC current of 1-23 A in a direction φ = 35° east of magnetic north through an open field. in a location where the Earth's magnetic field is horizontal and its strength is B = 0.57 G -Δ 17% Part (a) Calculate the magnitude of the magnetic force per unit length, F/l, in newtons per meter, exerted on the wire due to the Earth's magnetic ficld Δ 17% Part (b) In what direction does the force on the wire act? -Δ 17% Part (c) You decide to re-orient the wire to minimize the magnetic force acting on the wire. In what direction(s) could the current flow? -Δ 17% Part (e) which of the directions that correctly answer part (d) is the magnetic force on the wire up? -쇼 17% Part (f) If the wire is oriented so that the current flows in the direction you chose for part (e), what would the mass per unit length of the 17 % Part (d) In what direction(s) could you orient the current flow to maximize the magnetic force acting on the wire? wire, fu, in grams per meter, need to be for the magnetic force to balance the weight of the wire?
