Question

Which of the following is FALSE concerning the magnetic field created by a solenoid? (Choose one)

a) The magnetic field is much stronger inside the solenoid than outside the solenoid.

b) The strength of the magnetic field is proportional to the current through the windings of the solenoid

c) Each magnetic field line runs through the solenoid and then comes back around in the space outside the solenoid to form a closed loop.

d) Doubling both the number of windings and the length of a solenoid while keeping the current fixed will increase the strength of the magnetic field.

e) The magnetic field is approximately uniform within the interior volume of the solenoid.

Explanation / Answer

Ans D is False

The formula for magnetic field inside the solenoid = NI/L

hence if we double N and L and keep the I constant then there will be no change in magnetic field.
