According to your friend, what happens when the magnetic flux increases slightly? Choose all that apply 8 The induced current will increase continuously. O None of the other answers 10 The induced emf will get larger. The coil will get hot and eventually melt. 3 1 point A closed loop of wire is moved through a magnetic field such that the magnetic flux through the loop over time is represented by the graph below.
