Practice questions

1 of 39Practice questions for this set
A solenoid (coil of insulated wire) is connected to a variable DC power supply to investigate how current creates a magnetic field like a bar magnet. When current flows, the solenoid produces a magnetic field along its axis. If the current through the solenoid is increased from 0.5 A0.5\,\text{A} to 1.5 A1.5\,\text{A} while the number of turns stays the same, what happens to the solenoid's magnetic field strength (qualitatively)?
