Using AmpereÂ’s circuital law, obtain the expression for the magnetic field due to a long solenoid at a point inside the solenoid on its axis. A straight wire of length L is bent into semi-circular loop. Use Biot-Savart law to deduce an expression for the magnetic field at its centre due to current I passing through it.
