9. 10. The figure below shows four views of a horseshoe magnet and a straight wire in which electrons are flowing out of the page, perpendicular to the plane of the magnet. In which case will the magnetic force on the wire be directed upwards? A) a B) b C) c D) d Wire ÜÜ (a) (b) N Co (c) S • N (d) A long wire carrying 4.50 A of current makes two 90 bends, as shown in the figure. The bent part of the wire passes through a uniform 0.248 T magnetic field directed as shown in the figure and confined to a limited region of space. Find the magnitude and direction of the magnetic force on the wire? Magnetic field region 30.0 cm 4.50 A . 60.0 cm- B 60.0 cm A) 0.749 N, 63.4° clockwise from the right direction. B) 0.749 N, 63.4° counterclockwise from the right direction. C) 0.670 N, 63.4° clockwise from the right direction. D) 0.670 N, 27.6° clockwise from the right direction E) 0.335 N, 63.4° counterclockwise from the left direction
