Investigate the relationship between electromagnet strength and amount of current flowing through the wire.

... Investigate the relationship between electromagnet strength and amount of current flowing through the wire. 1. PLAN: Diagram: The Experiment: I set up the equipment as shown in the diagram above. I put the variable resistor in the circuit to vary the current flow. I put the ammeter in the circuit to measure current flow at certain points. I then added an electromagnet to show that when electricity flows through a wire wrapped around a magnetically soft iron core, a magnetic field is created. I also added the electromagnet because we needed it to investigate the relationship between electromagnet strength and the amount of current flowing through the wire. Moreover, I added a battery consisting of 3 cells to provide electrical energy to the circuit. Furthermore, I added a load to the electromagnet to provide a measurement of magnetic strength of the electromagnet. Finally, I needed the clamp stand to hold the electromagnet and
