Question

OR
Observe the figure given below and answer the following questions:
000000
(a) Write the special name given to the coil AB which has many circular
turns of insulated copper wire.
(b) State the nature of magnetic field inside AB when a current is passed
through it.
(c) Draw the diagram showing the pattern of magnetic field lines through
and around AB,
(d) List two factors on which the strength of the magnetic field produced
by AB depends.
(e) What is the effect of placing an iron core in the coil AB?​

Answer 1

Explanation:

(a) solenoid

(b) magnetic field lines are parallel to each other at every point.ie magnetic field is same at all points

(d) it depends on current and number of circular turns

Answer 2

(The diagram missing in the question is attached below}

From the figure the following observations were made

(a) The coil AB can be called as a solenoid which has many turns of insulated copper wire.

(b)Uniform magnetic field is produced inside AB when a current is passed through it

(c) The diagram showing the pattern of magnetic field lines through and around AB is attached below

(d) The strength of magnetic field produced depends on the magnitude of the current flowing and number of turns in the coil
