Question

Which changes will cause an increase in the magnetic field of a solenoid?

1) Using more wire loops
2) Using a larger current
3) Decreasing the spacing between loops

Answer 1

Answer: 1) Using more wire loops

Explanation: More wire loops increases the magnetic field of the solenoid.

Answer 2

To increase the magnetic field of a solenoid, you can use more wire loops, a larger current, or decrease the spacing between loops.

Step-by-step explanation:

To increase the magnetic field of a solenoid, you can:

1. Use more wire loops. The magnetic field produced by a solenoid is directly proportional to the number of wire loops, so increasing the number of wire loops will increase the magnetic field.
2. Use a larger current. The magnetic field produced by a solenoid is directly proportional to the current flowing through it, so increasing the current will increase the magnetic field.
3. Decrease the spacing between loops. The magnetic field produced by a solenoid is inversely proportional to the spacing between loops. By decreasing the spacing between loops, the magnetic field will increase.
