Sketch the magnetic field due to (i) a circular coil and (ii) a solenoid. What are important characteristics of the field produced by each?

Magnetic Field due to Circular Coil

Magnetic Field due to Circular Coil

Draw the magnetic fields formed due to Circular coil carrying current.

Why can't two magnetic field lines cross each other? Draw the magnetic field lines (including field directions) of the magnetic field due to a long straight solenoid. What important property of this field is indicated by this field line pattern? Name any two factors on which the magnitude of the magnetic field due to this solenoid depends.

Magnetic Field Due to Circular Loop||Ideal Solenoid

Compare the magnetic fields due to a solenoid and a bar magnet.

The magnetic field due to a current-carrying solenoid is independent of
