Final answer:
Increasing the number of loops in a current-carrying wire coil results in a stronger magnetic field, as each loop adds to the total field strength.
Step-by-step explanation:
As the number of loops in a current-carrying wire coil is increased, the magnetic field becomes stronger. This is because each additional loop of the coil contributes to the overall strength of the magnetic field inside the coil, leading to a cumulative effect that enhances the magnetic field produced. The magnetic field lines inside such a solenoid are much denser compared to the outside, making the magnetic field within the solenoid stronger. Moreover, the induced electromotive force (emf) is N times stronger in a coil made from N loops compared to a single loop, assuming a changing magnetic field.
Therefore, the relationship between the number of wire loops and the magnetic field strength is direct. As noted in various physics findings, the magnetic field strength at the center of a current-carrying loop can be calculated, but the cumulative effect of multiple loops results in a significantly stronger magnetic field.
