Technician A is correct. Increasing the amount of current flowing through a conductor will increase the strength of its magnetic field according to the right-hand rule.

Technician B is also correct. Coiling a wire around a soft iron core will create an electromagnet with a stronger magnetic field than a single wire. This is because the soft iron core increases the magnetic field by concentrating it in a smaller area.
