Predict/Explain The number of turns in a solenoid is
Chapter 22, Problem 56(choose chapter or problem)
Predict/Explain The number of turns in a solenoid is doubled, and at the same time its length is doubled. Does the magnetic eld within the solenoid increase, decrease, or stay the same? (b) Choose the best explanation from among the following: I. Doubling the number of turns in a solenoid doubles its magnetic eld, and hence the eld increases. II. Making a solenoid longer decreases its magnetic eld, and therefore the eld decreases. III. The magnetic eld remains the same because the number of turns per length is unchanged.
