A long wire carrying 1 Amp lies in the xy plane and makes an angle of 45 degrees from the x axis. The wire passes through a uniform magnetic field B= (1 xˆ + 2zˆ) T. Determine the components of the force on the wire per cm of length. (Hint: Breakdown the force law for magnetic fields into into its individual components and consider them separately)
