Please Write Step by Step Solutions. Not just the answers only. Question 1 A square loop of wire surrounds a solenoid. The side of the square is 0.1 m, while the radius of the solenoid is 0.025 m. The square loop has a resistance of 30 . The solenoid has 500 turns and is 0.3 m long. The current in the solenoid is increasing at a constant rate of 0.7 A/s. What is the current flowing in the square loop? I = A Question 2 True or false: (a) The induced emf in a circuit is proportional to the magnetic flux through the circuit. true false [2.5 points] 0 attempt(s) made (maximum allowed for credit = 1) (b) There can be an induced emf at an instant when the flux through the circuit is zero. true false [2.5 points] 0 attempt(s) made (maximum allowed for credit = 1) (c) Lenz's law is related to the conservation of energy. true false [2.5 points] 0 attempt(s) made (maximum allowed for credit = 1) (d) The inductance of a solenoid is proportional to the rate of change of the current in it. true false Question 3 A circular coil of 14 turns of radius 6 cm is in a uniform magnetic field of 4000 G in the positive x direction. Find the flux through the coil for the following orientations of the unit vector n that is perpendicular to the plane of the coil. (a) n = i Wb [2 points] 0 attempt(s) made (maximum allowed for credit = 5) [after that, multiply credit by 0.5 up to 10 attempts] (b) n = j Wb [2 points] 0 attempt(s) made (maximum allowed for credit = 5) [after that, multiply credit by 0.5 up to 10 attempts] (c) n = (i + j)/ 2 Wb [2 points] 0 attempt(s) made (maximum allowed for credit = 5) [after that, multiply credit by 0.5 up to 10 attempts] (d) n = k Wb [2 points] 0 attempt(s) made (maximum allowed for credit = 5) [after that, multiply credit by 0.5 up to 10 attempts] (e) n = 0.9 i + 0.435889894354067 j Wb Question 4 A circular coil of 14 turns of radius 6 cm is in a uniform magnetic field of 4000 G in the...
