1. A magnetic field of 0.0200 T [up] is created in a region. (5 marks) a) Determine the magnitude and direction of the initial magnetic force on an electron initially moving at 5.00 x 106 m/s [N] in the field. b) What is the radius of the circular path of the electron? 2. A magnetic field of 1.4 T [N] is 4.0 m wide. A very long wire crosses the field. (6 marks) a) If the current in the wire is 2.0 A [W], find the magnetic force on the wire. b) What will happen to the force on the wire if: (i) the wire is rotated slightly in the horizontal plane? (ii) the current is doubled? (iii) the magnetic field is reversed?
