What is magnetic field outside solenoid ?

Out of the following , which statement is wrong for a current - carrying solenoid ?

Whose magnetic field resembles the magnetic field of a current - carrying solenoid ?

(b) Magnetic field lines can be entirely confined within the core of a toroid, but not within a straight solenoid. Why ?

2 A current is passed through a solenoid which has 5 cm diameter, 10 turns and 10 cm length. Now, near to one of its two ends, a circular loop of radius 2 cm is kept perpendicular to axis of solenoid. Then magnetic flux passing through this loop is ...... Wb. ( mu_0=4pixx10^(-7)TmA^(-1) and take pi^@ =10)

A solenoid of length 3.14 cm has a radius of 1 cm and is made up of 500 turns. It carries a current of 5 A. What is the magnitude of the magnetic field inside the solenoid ?

A solenoid of length 0.4 m has a radius of 1 cm and is made up of 500 turns. It carries a current of 10 A. What is the magnitude of the magnetic field inside the solenoid ?
