What is solenoid?

What is a solenoid? Explain with a diagram Refer to the magnetic field produced by a current carrying solenoid.

Toroid is a solenoid of

At which point on the axis of solenoid is the magnetic field maximum?

A closely wound solenoid of 2000 turns and area of cross-section 1.6 xx 10^-4 m^2 ,carrying a current of 4.0 A,is suspended through its centre allowing it to turn in a horizontal plane. What is the magnetic moment associated with the solenoid ?

Draw the magnetic force lines of a current carrying finite solenoid?

A solenoid 1 m long and 4 cm diameter possesses 10 tums//cm . A current of 5A is flowing through it. Calculate the magnetic induction:- at one end on the axis of solenoid.

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

What is energy? What is its unit?

Complete the diagram of magnetic lines of force passing through a solenoid

What is the nature of the magnetic field inside the solenoid?
