The magnetic field inside a long straight solenoid-carrying current
is uniform inside the solenoid
Correct Answer: (d) is uniform inside the solenoid
Explanation: The magnetic field inside a solenoid is uniform and parallel to its axis, irrespective of the position inside it.
The magnetic field inside a long straight solenoid-carrying current
The magnetic field lines inside a current carrying long solenoid are in the form of
A square loop of side $1$ m and resistance $1 \Omega$ is placed in a uniform magnetic field of $0.5$ T. If the plane of the loop makes an angle of $30^\circ$ with the direction of the magnetic field, the magnetic flux through the loop is:
