Q. Q- If we consider the magnetic field of bar magnet is same as the magnetic field of solenoid. Then why the field at the poles of bar magnet is strong than any other point while magnetic field at the ends of solenoid is half of the field at middle?

Q. Assertion :The magnetic field at the ends of a very long current carrying solenoid is half of that at the centre. Reason: If the solenoid is sufficiently long, the field within it is uniform.

Q. Question 10
The strength of magnetic field inside a long current carrying straight solenoid is

(b) minimum in the middle
(c) same at all points
(d) found to increase from one end to the other

Q. A current carrying solenoid, acting as a short bar magnet, produces a magnetic field around it. The distance of a point

P

at its perpendicular bisector is

R

from its centre and another point

A

at its axis is situated at

4R

from its centre. Then find the ratio of magnetic field at

A

to the magnetic field at
