2. The circuit in the figure below is located in a magnetic field whose magnitude varies with time according to the expression B = 1.00 x 10-³t, where B is in teslas and t is in seconds. Assume the resistance per length of the wire is 0.105 Q/m. (a) Find the current in section PQ of length a = 58.0 cm. (b) What is the direction of the magnetic force on the section PQ? * * ** a * * * * Bin ***** xxxxxxxx 2a P * * * * 07 **** ****
