The magnetic field inside a long straight current carrying solenoid :

Observe the given figure of Fleming' s Right Hand Rule and write the labels of A and B correctly.

Describe the magnetic field produced by a solenoid carrying current.

The diagram shows a current carrying wire passing through the centre of a square card board. The magnetic field at points $A$, $B$  and $C$ is:

The diagram below shows a magnetic needle kept just below the conductor AB which is kept in the North-South direction.

i) In which direction will the needle deflect when the key is closed?

ii) Why is the deflection produced?

iii) What will be the change in the deflection if the magnetic needle is taken just above the conductor AB?

iv) Name one device which works on this principle.

Kunal draws magnetic field lines close to the axis of a current carrying circular loop. As he moves away, towards the centre of the circular loop, he observes that the lines keep on diverging. How will you explain his observation?

What is a solenoid? Can you determine the North and South poles of a current-carrying solenoid with the help of a bar magnet? Explain.

A constant current I flows in a horizontal wire in the plane of the paper from West to East as shown in the figure. The direction of magnetic field at a point will be South to North

Electricity and magnetism are linked to each other.
Why does a current carrying solenoid when suspended freely rest along a north-south direction?
