Question

1. identify what are two things you can do to make the magnetic field of a solenoid stronger?

Explanation:

The magnetic field strength of a solenoid ($B$) is given by the formula $B = \mu_0nI$, where $\mu_0$ is the permeability of free space, $n=\frac{N}{L}$ (number of turns per unit length, $N$ is the total number of turns, $L$ is the length of the solenoid), and $I$ is the current. Increasing $n$ (by adding more turns $N$ while keeping $L$ constant or decreasing $L$ with $N$ constant) or increasing $I$ will make $B$ stronger.

Answer:

Increase the number of turns in the solenoid. Increase the current flowing through the solenoid.
