A loop of wire in the shape of a rectangle of width w and length L and a long, straight wire carrying a current I lie on a tabletop as shown in the figure below. TU L (a) Determine the magnetic flux through the loop due to the current I. (Use any variable stated above along with the following as necessary: Ho.) Ф ЕВ (b) Suppose the current is changing with time according to I = a + bt, where a and b are constants. Determine the magnitude of the emf in V) that is induced in the loop if b = 20.0 A/s, h = 1.00 cm, w = 20.0 cm, and L = 1.50 m. V (c) What is the direction of the induced current in the rectangle? O clockwise O counterclockwise O 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 = 18.0 cm/s. (d) What is the magnitude of the induced emf (in V) in the loop 1.00 s after it begins to move? (e) What is the direction of the induced current in the loop 1.00 s after it begins to move? O clockwise counterclockwise O The magnitude is zero.
