The coil is placed in a spatially uniform magnetic field of magnitude 0.30 T so that the face of the coil and the magnetic field are perpendicular. Find the magnitude of the emf induced in the coil (in V) if the magnetic field is reduced to zero uniformly in the following times. (a) 0.40 s -0.225 X V (b) 4.0 s (c) 50 s Additional Materials Reading Submit Answer 2. [-/1 Points] DETAILS OSUNIPHYS1 29.2.P.022.

MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER How far from the starter cable of a car, carrying 135 A, must you be to experience a field less than the Earth's (4.80 x 10 5 T)? Assume a long, straight wire carries the current. (In practice, the body of your car shields the dashboard compass.) m Additional Materials Reading Submit Answer 4. [-/4 Points] DETAILS OSUNIPHYS1 29.2.WA.010. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER As shown in the figure below, two long parallel wires (1 and 2) carry currents of I, = 2.88 A and I2 = 5.35 A in the direction indicated. (a) Determine the magnitude and direction of the magnetic field at a point midway between the wires (d = 10.0 cm). magnitude direction . counterclockwise from the +x axis (b) Determine the magnitude and direction of the magnetic field at point P, located d = 10.0 cm above wire 1. magnitude HT direction counterclockwise from the +x axis Additional Materials Reading
