First, slowly move the magnet into the shorter coil of wire (the coil near the top). What happens to the voltage when the magnetic field lines that are closer together (at the North and South Poles) move through the wire, compared to when the middle of the magnet moves through the coil

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.

a is the best answer your welcome

the answer you are looking for is d. there are no holes for blood to enter or leave the system. your welcome

it would stay the same
