Magnetic Field Inside a Solenoid:
The magnetic field inside a long solenoid is uniform and parallel to the axis of the solenoid.
The field strength is given by the formula:
B = μ0 × n × I
Characteristics:
The field inside the solenoid is uniform and does not vary along its length (except near the ends).
Outside the solenoid, the magnetic field is nearly zero for an ideal solenoid.
∴ The correct answer is Option 4: The magnetic field inside a long straight solenoid carrying current is uniform.
