13. You have decided to use a magnetic field in combination with an electric field as a switch to either make a beam of electrons pass straight through a certain region of an apparatus or to curve 90° and go through an auxiliary portion of the apparatus. The beam of electrons travels to the right at a speed of 4.8 x 106 m/s and you designed the electric field (8400 V/m) to be oriented 10⁰ vertically up. a) When the electric field is on, what strength of B-field is necessary for the beam to travel un-deflected? (Note: You can ignore gravity.) b) What is the orientation of the B-field? c) When the electric field is turned off, how long does it take an electron to turn into the auxiliary apparatus?

5. The magnitude of the magnetic field around a single current-carrying wire with current I, Hol is given be B = where 4= 47 × 10-7 T·m/A. The formula for the force on a single 2πη current-carrying wire with current I, is F = ILB, if the current is perpendicular to the magnetic field. What is the magnitude of the force between two parallel wires, each carrying a 1A current, if the wires are 10 m long and 2 m apart.
1. Explain why the magnetic field would not be unique (that is, not have a single value) at a point in space where magnetic field lines might cross. (Consider the direction of the field at such a point.) List the ways in which magnetic field lines and electric field lines are similar. For example, the field direction is tangent to the line at any point in space. Also list the ways in which they differ. For example, electric force is parallel to electric field lines, whereas magnetic force on moving charges is perpendicular to magnetic field lines.
