A) Earth magnetic shieldi) What will happen to the solar particles as the particles enter magnetosphere ii) With the aid of a diagram, determine the direction of a proton as it enters Earth’s magnetic field.iii) An electron is moving through a magnetic field whose magnitude is 6.5x10-4 T. At a certain instant, when its speed is 5.5x106 ms-1, It experienced an acceleration of magnitude 3.0x1015 ms-2. Determine the angle θ between the electron’s velocity and the magnetic field. B) Force on a current carrying conductor in a magnetic field – Physicsi) Explain how magnetic field can be produced around a conductor.ii) With the aid of suitable diagrams, show the directions of the rod before and after reversing the current. iii) What is the condition for force to be at maximum value? C) Force Between Two Long Parallel Current Carrying Conductors i) How do you relate between magnetic field from current carrying wires with force felt by a current carrying wire?ii) Two wires, each having a weight per unit length of 2.00x10-3 N/m, are parallel with one directly above the other. Assume the wires carry currents that are equal in magnitude and opposite in direction. The wires are 0.10 m apart, and the sum of the magnetic force and gravitational force on the upper wire is zero. Find the current in the wires.
