Students built two electromagnets. The electromagnets are the same except that one has 20 wire coils around its core, and the other has 40 wire coils around its core. Which is the best comparison?(1 point)
The electromagnet with 20 coils will be stronger than the electromagnet with 40 coils.
The electromagnet with 40 coils will be exactly twice as strong as the electromagnet with 20 coils.
The electromagnets will be equally strong.
The electromagnet with 40 coils will be stronger than the electromagnet with 20 coils.

The electromagnet with 40 coils will be stronger than the electromagnet with 20 coils.
Reason: More turns of wire increase the magnetic field (for the same current), so the coil with 40 turns produces a stronger magnet.
