SUMMARY
The discussion centers on calculating the magnetic field strength (B) of an electromagnet with 60 turns of copper wire using a variable voltage source. The relevant equation for determining B in the presence of a soft iron core involves the relative permeability of the material. The relative permeability constant for soft iron is typically around 200 to 5000, depending on the specific alloy. For precise calculations, refer to the solenoid formula provided in the linked Wikipedia article.
