- Considering the magnetic force law, are velocity and the magnetic field always perpendicular?Are the magnetic force and velocity always perpendicular? What about the magnetic force andmagnetic field? Explain your answer.An alpha particle (a helium nucleus which has a net positive charge) is moving due east when it enters a magnetic field that is directed due north. Which one of the following statements best describes the motion of the alpha particle after entering the magnetic field? O The particle continues at a constant speed, but its direction changes as it follows a circular path toward the north. The particle slows and changes direction to accelerate to move upward. O The particle continues at a constant speed, but its direction changes as it follows a circular path upward. O The particle continues at a constant speed, but its direction changes as it follows a circular path downward. O The particle slows and changes direction to accelerate to move downward.In which direction does the wire feel the force (F)? Highlight one option.

- Two long straight current-carrying wires are lined up parallel to one another in vacuum at a distance d. Currents of I and I2 flow through the wires, both in the same direction generating the field of BM at a midpoint between them. Write down an expression for BM in terms of the currents running in each of the wires. Assume vacuum permeability µo = 1. Please "*" for products (e.g. B*A), "/" for ratios (e.g. II *II use B/A) and the usual "+" and "-" signs as 1 appropriate. For R use 1/(A*B). For Greek A*B letters such as 1 or t use lambda and pi.
