PLEASE ANSWER ALL PARTS

a. A circular coil of wire with 7 loops and a radius of 0.041 m is placed inside a solenoid. The coil is aligned so that the normal to the coil is parallel to the magnetic field in the solenoid. The solenoid consists of 40000 loops of wire and is 0.18 m long. Initially a current of 0.5 A runs through the solenoid. The current is increased to 4.5 A over a period of 4.1 s. What is the initial magnetic flux through the coil?

b. What is the final magnitude of the magnetic field inside the solenoid?

c. What is the MAGNITUDE of the average electromotive force (EMF) induced in the coil while the magnetic flux is changing? What is the final magnetic flux through the coil?

d. If the coil of wire has a resistance of 10 Ω, what is the MAGNITUDE of the induced current in the coil?
