Question

The magnetic field inside a solenoid is proportional to the diameter of the solenoid. Select one: a.True b. False

Expert Solution

Step 1

To determine: The correct option.

Step 2

Explanation:

Magnetic field inside a solenoid can be defined as:

$B = \frac{μ_{0} N I}{L}$

Here, $N$ is the number of turns, $I$ is the current, $L$ is the length.

So, it can be concluded that magnetic field inside a solenoid is directly proportional to the current as well as number of turns per unit length. Hence, the given statement is false.

The correct option is b. False.
