4. (-/4 Points) DETAILS SERPSE10 30.1.OP.009.DEFECTIVE MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER A loop of wire in the shape of a rectangle of width w and length and a long, straight wire carrying a current Ille on a tabletop as shown in the figure below (a) Determine the magnetic flux through the loop due to the current I. (Use any variable stated above along with the following as necessary: Mo.) (b) Suppose the current is changing with time according to I-+bt, where a and b are constants. Determine the magnitude of the emt (in V) that is Induced in the loop if b = 16.0 A/S, n = 1.00 cm, w - 20.0 cm, and L = 1.35 m. V
(c) What is the direction of the induced current in the rectangle? O clockwise counterclockwise The magnitude is zero What If? Suppose a constant current of I - 6.00 A flows in the straight wire and the loop moves from an initial position ho - 1.00 cm toward the bottom of the figure at a constant speed of v 24.0 cm/s. (a) What is the magnitude of the induced emf (in V) in the loop 1.00 s after it begins to move? (@) What is the direction of the induced current in the loop 1.00 / after it begins to move? O clockwise O counterclockwise The magnitude is zero. Need Help? Watcht
