Through these experiments, you concluded that:

1. There is a direct relationship between electricity and magnetism. The flow of current through a wire generates a magnetic field perpendicular to the wire. As the amount of current flowing through the wire increases, the magnitude of the magnetic field increases. As current increased from 1.88 A to 2.24 A, the magnitude of the magnetic field increased from 15762 × 10-7 T to 18781 × 10-7 T, allowing the number of paper clips attracted to the magnet to increase from 1 to 4.
2. The strength of an electromagnet is affected by the number of turns of wire in the coil over a specific length. The strength of an electromagnet is also affected by the amount of current flowing through the wire. As the number of turns of wire in the coil increases, the strength of the electromagnet increases. Decreasing the number of turns of wire decreases the strength of the electromagnet. Increasing the current also increases the strength of the electromagnet. Decreasing the amount of current decreases the strength of the electromagnet.
