Question 4 If you wanted to minimize the force exerted on a current-carrying wire by the Earth's magnetic field, what could you do? O align the write with Earth's magnetic field lines. O align the write to be perpendicular to Earth's magnetic field lines. O align the write to make a 45 degree angle with Earth's magnetic field lines. O None of the above.Question 5 How does the magnetic force exerted on a current-carrying wire depend on its length? O The force is smaller for longer wire. The force is greater for longer wire. O The force does not depend on the length. None of the above.Question 6 If a current runs through a wire in the direction of 2, and a magnetic field points in the direction of -y. What direction will the force exerted on the wire point? O +i O O +2 O -2 O O None of the above
