Describe the change in the magnetic field in the interior of a solenoid carrying a steady current I for the following cases.
Case a) The length of the solenoid is doubled but the number of turns remains the same.
1. the magnetic field is cut in half.2. the magnetic field is cut to a quarter.3. the magnetic field is quadrupled.4. the magnetic field does not change.5. the magnetic field is doubled. Case b) The number of turns is doubled but the length remains the same.1. the magnetic field does not change.2. the magnetic field is doubled.3. the magnetic field is quadrupled.4. the magnetic field is cut to a quarter.5. the magnetic field is cut in half.
