(a) A current of 3.0 A flows vertically down each of

(a) A current of 3.0 A flows vertically down each of 2 long wires which are mounted side by side 5 cm apart. i. Show on a diagram the magnetic field pattern in a horizontal plane, indicating clearly the direction of the magnetic field at any point. li. What is the direction and magnitude of the magnetic force on a 25 cm length of wire? (b) The two long vertical wires are now moved 030 m apart and placed left-right of one another. The current in the left wire is set to 20 A and the current in the right to 30 A. Both currents flow upwards. If the horizontal component of the Earth's magnetic field him a flux density of 2.0 x10 and the equation for flux density around a wire (8..) = Calculate the resultant force on each metre of the left wire
