20. A wire 25 cm long with an north-south orientation carries a current of 3.0 A southward. There is a uniform magnetic field perpendicular to this wire. If the force on the wire is 0.33 N upward, what is the magnitude and direction of the magnetic field? (Note: East-west and north-south are in the page, up-down are perpendicular to the page). a) 0.44 T, Up b) c) 0.0044 T, Up d) 0.44 T, East e) 0.44 T, West 0.0044 T, East
