A rectangular loop of wire that can rotate about an axis through its center is placed between the poles of a magnet in a magnetic field with a strength of 0.40 T, as shown in the figure. The length of the loop Lis 0.16 m and its width w is 0.040 m. What is the magnetic flux through the loop when the plane of the loop is parallel to the magnetic field? 300 Select one: Oa 13-10 T-m2 Ob 0.80 T-m2 Oc 26x10 T-m2 Od. OT-m2 Oe 26×10¹T-m2
Question/ Answer seve 12 As shown in the figure, a particle of charge 1.9 x 10°C and mass 3.1 x 10 kg has speed 8.1 x 10 cm/s enters a region of uniform magnetic field. The particle is initially traveling perpendicular to the magnetic field and is observed to travel in the semicircular path shown with radius R-5.0 cm. Find the magnitude and direction of the magnetic field in the region Region of magnetic field Select one: Oa 26 T, into the paper Path of the particle
