Electromagnets lab

Main activity
Uncovered copper is stronger for an electromagnet as it only took 13 coils of tightly wrapped copper to pick up 4 paperclips, but it took 20 coils of the covered wire to carry only 1, lower temprature electromagnet has better magnetic potential as observed, after using a nail for an electromagnet it gets magnetic properties, tightly grouped coils also seem to make the electromagent stronger, stronger cores in the metal affect how strong the electromagnet

Pre-Activity
Once a compass is near a full circut it starts to move out of control despite not moving, this can be explained by the magnet field surrounding the wire.
